BAK Industries (BakFlip) has been leading the tonneau cover market since 1982. Founded by Dave Bak and now part of Truck Hero, BAK is known for American-made, heavy-duty truck bed covers.
With decades of innovation, BAK offers a range of folding and roll-up designs built from aircraft-grade aluminum and rugged composites.
Every cover is engineered for durability and security, featuring seamless weather seals, integrated latches or locks, and a sleek low-profile look.
BAK’s product lineup – from the premium MX4 series to the value-friendly G2 and the rugged FiberMax – covers full-size pickups and midsize trucks alike.
In this guide, we break down the Top 10 BAK tonneau covers, detailing each model’s key features, pros/cons, build quality, fitment, and real-world use.
We’ll also explain how to choose the right BAK cover by considering materials, bed size, locking mechanism, and your specific needs (work truck vs daily driver).
Top 10 BAK Tonneau Covers
1. BAKFlip MX4 Hard Folding Tonneau Cover
The BAKFlip MX4 is BAK’s flagship hard-folding cover. It features heavy-duty, matte-black aluminum panels bonded to a high-density foam core, forming a sturdy barrier over the bed.
The MX4 is no-drill, clamp-on install (under 30 minutes) and boasts a 400-lb evenly distributed weight capacity. When closed, it sits flush with the bed rails for a stealthy, low-profile look.
Each panel has a spring-loaded hinge and auto-latching rods, so one person can fold or unfold the cover with one hand.
It fully folds against the cab for 100% bed access, and a dual-action tailgate seal (13% longer on Gen3) maintains factory tailgate function.
The cover is weatherproof, with revised EPDM seals around the edges and an integrated drain system to keep water out.
Construction quality is top-notch: reinforced rails, upgraded latch components, and powder-coat protection ensure long life.
Key Features
Fitment
Real Use: Owners praise the MX4’s solid build and security – theft-proof locking rails mean the bed is protected under a locked tailgate. Its matte finish blends with the truck’s look. The clamp-on rails and revised prop-rod clips hold the cover tightly, so even heavy gear stays dry. Many note that installation and removal are easier than expected, and the cover feels “solid as a vault” when closed.
2. BAKFlip G2 Hard Folding Tonneau Cover

Constructed of solid-core aircraft-grade aluminum panels, it supports up to 300 lbs evenly. Like the MX4, the G2 clamps on (no drilling) and folds toward the cab for full access.
One standout feature is its integrated LED high-mount brake light (on select Silverado/Sierras) or compatibility with factory light wires, improving visibility. The G2’s panels latch automatically via spring-loaded cables; simply pull a release cable to fold.
All surfaces have a textured semi-gloss black finish that is durable and resists UV. The rails and bumpers (rubber) protect the cab when folded up.
Water is funneled away by EPDM side seals and an under-panel drain system. Compared to the MX4, the G2 has slightly lighter construction but still offers solid protection and weatherproofing.
Key Features
Fitment
Real Use: The G2 is a crowd favorite for its blend of durability and price. DIYers note it installs hassle-free (clamps lock in place, then tighten). In use, the G2 covers haul bike gear, tools, and cargo without letting rain in. The automatic latch system is praised – panels snap shut firmly and only require pulling the cable to open. The flush styling and optional light make it popular for daily drivers who want security and a factory look.
3. BAKFlip F1 Hard Folding FRP Cover
The BAKFlip F1 is a heavy-duty folding cover with a fiberglass-reinforced polymer (FRP) top and aluminum frame. Its FRP panels are 0.25″ thick solid-core material that resists dents, UV fading, and corrosion. This cover also clamps on with no drilling.
The F1 holds up to 400 lbs evenly (same as MX4), making it one of BAK’s strongest covers. Each panel latches with robust slam-style catches that automatically lock when closed; a pull release cable lets you fold the cover forward.
Weather seals and rubber bumpers protect the cargo from rain and the cab when folded. While the F1 does not include a brake light, it does lock: the tailgate key acts as the sole entry into the bed when the cover is closed, providing theft protection.
The F1’s all-black finish and integrated latches give it a clean look, but it is a bit heavier due to the FRP.
Key Features
Fitment
Real Use: Contractors and off-roaders favor the F1 for its ruggedness. Users report it holds up to heavy tools and ladders on top without damage. The latch system is very secure, and with the keyed lock, thieves can’t roll it up. The FRP finish stays looking new even in sun and mud. Many say it’s “built like a tank” – once installed, it’s essentially maintenance-free.
4. BAKFlip FiberMax Hard Folding Cover
The BAKFlip FiberMax is the budget-friendly hard folding cover in the BAK lineup. It shares the FRP (fiberglass-reinforced polymer) panel design with the F1 but has slightly lighter materials.
Its panels still offer strong weather resistance and a dent-free exterior. The FiberMax clamps to the bed (no drilling), and each panel auto-latches with a cable release.
It provides good cargo protection and partial weather sealing (EPDM seals and bumpers).
Unlike F1, the FiberMax does not lock the tailgate – it functions like a cover only. Its lower price makes it appealing for drivers who need a solid cover but don’t need maximum load support.
Key Features
Fitment
Real Use: Many first-time buyers get the FiberMax for its value. Users report it functions well as a basic cover – it folds smoothly and does its job of protecting cargo. It’s lighter, so install is very simple. Drivers note that it’s almost as good as higher-end models for casual use: it seals out rain, looks sleek, and the no-drill clamps hold firm. If you’re hauling light gear and don’t need heavy-duty performance, FiberMax is a solid pick.
5. BAKFlip CS Cover & Rack System
The BAKFlip CS (Contractor Series) is a unique combo: a heavy-duty tonneau cover (your choice of F1 or G2) integrated with an adjustable ladder rack. This system is built for contractors, cyclists, and outdoorsmen who need both covered storage and an overhead rack.
The CS installs on trucks with factory Cargo Management rails (Deck rail system) using clamps (no drilling). You can slide the rack uprights forward or back along the rails for different uses.
The rack holds up to 500 lbs (evenly spread) on top of the BAK roof panels, which themselves support 300-400 lbs. The F1 option adds FRP panels (400-lb rating) while the G2 option uses aluminum (300-lb rating).
When closed, the cover and rack together lock out cargo: the tailgate key secures the entire setup. If you need full bed access, the cover easily folds up, and the rack can be removed or slid forward.
Key Features
Fitment
Real Use: For work trucks, the CS is a game-changer. Truck owners hauling construction gear love the integrated rack: it replaces roof racks or bulky ladder sets while keeping gear secure. They note that the cover part still provides full bed coverage and locks, so nothing gets stolen or wet.
The sliding ability allows either carrying tall cargo or pulling cargo to the tailgate for access. Enthusiasts also use it for carrying bikes on top (with bike mounts), then folding the cover to protect gear below.
In summary: If you need both a lockable bed cover and a heavy-duty overhead rack, the CS hits the mark – no competitor does both at this level.
6. BAK Revolver X4s Hard Roll-Up Cover
White GMC Sierra with a BAK Revolver X4s hard roll-up cover partially rolled open, illustrating its rugged aluminum slats and vinyl top.The BAK Revolver X4s is the latest generation hard roll-up cover. It uses marine-grade vinyl stretched over interlocking aluminum slats.
A key feature is one-handed operation: simply grab the strap and pull to roll up the cover. It then secures at the front with durable buckle straps.
Unlike soft roll-ups, the X4s has no Velcro or snaps – it rolls on tracks. It’s built very tough: thick marine vinyl hides sturdy slats that resist cutting, and side rails include patented rotational auto-locking technology. When you latch it closed, the cover self-locks along its entire length.
The X4s also got a style upgrade: all components are matte black (vinyl, clamps, rails) for a stealthy look.
Weather seals are top-notch: full-length flat seals and a heavy bulkhead seal at the cab stop water infiltration. The X4s holds up to 400 lbs (evenly) on top and comes with a 5-year warranty.
Key Features
Fitment
Real Use: Owners rave about the one-hand convenience. After years of using strap and buckle covers, they appreciate how smooth and quiet the X4s is.
Many also highlight its security – the auto-latching rails mean even with the tailgate locked, thieves can’t lift the cover. Reviewers frequently mention it looks great on their truck, and it absorbs shocks and weather well.
For example, one camper says the thick vinyl kept rain out completely, and the integrated straps keep it stable while driving.
Installation is reported as straightforward – the clamp-on rails align and tighten easily. Overall, the X4s is recommended for those who want a high-end, low-maintenance roll-up cover with maximum durability.
7. BAK Revolver X4 Hard Roll-Up Cover
White GMC pickup with a BAK Revolver X4 hard roll-up cover fully closed, showing the sleek black vinyl surface.The BAK Revolver X4 is the previous-generation hard roll-up cover (superseded by the X4s).
It has many of the same strengths: a vinyl-topped aluminum slat design and a patented rotational locking rail. Like the X4s, it does not use Velcro or snaps. The X4 incorporates an automatic latch bar (slam latch) at the rear – just pull a cable to release from either side.
Once closed, the entire cover locks by the side rails when you lock the tailgate. It offers complete bed access when fully rolled to the front. The X4’s finish is a matte-black vinyl with matching hardware (though some parts may have gloss elements).
It also supports 400 lbs on top and carried the same 5-year warranty. In short, the Revolver X4 is a proven, ultra-secure roll cover that came just before the X4s update.
Key Features
Fitment
Real Use: Think of the X4 as the “classic” version of BAK’s roll-up covers. Users loved its robust build: one reviewer noted that once locked, “there’s no way anyone can sneak in – it’s locked tight.”
Another owner highlighted how quickly it rolls out of the way for hauling lumber or bikes, yet seals out rain just as well when shut. Installation is quick (clamps and a simple tailpiece align the rails) and the quality matches that of a premium cover.
If you find it on sale, it still offers excellent security and convenience even by today’s standards.
8. BAK Revolver X2 Hard Roll-Up Cover
The BAK Revolver X2 is the economy hard roll-up model, now largely superseded by the X4 series. It features a vinyl top over aluminum slats, but uses a simpler latch system.
To open the X2, you must first unlock and lift the tailgate, then detach two buckles at the front of the cover to roll it toward the cab. It secures in place with straps over the folded cover.
Since it predates the X4’s patented rails, the X2 does not lock with the tailgate closed – opening the cover requires lowering the tailgate. It offers good bed protection for the price, but with a lower weight capacity (typically ~300 lbs).
Installation is still easy (clamp-on) and the cover includes weather seals and side rails. For budget buyers, the Revolver X2 delivers basic function: it keeps rain and dust out, rolls up fully for access, and is one step up from soft covers.
Key Features
Fitment
Real Use: The X2 is chosen by buyers on a tight budget who still want the benefits of a hard cover. They report that for everyday chores, it’s quite capable: it sheds rain well and stays in place while driving.
Its main limitation is security – since you have to drop the tailgate, it won’t keep thieves out if you leave the tailgate unlocked.
Also, users note you have to be careful rolling it evenly so it doesn’t jam. Overall, it’s a solid entry-level roll-up: better than canvas covers, but lacking the bells and whistles of higher-end BAK models.
9. BAKBox 2 Tonneau Toolbox
BAKBox 2 fold-away tonneau toolbox mounted in a truck bed, with the lid open revealing an internal sliding tray holding tools.The BAKBox 2 is a different kind of bed cover – a lockable toolbox that sits between the wheel wells. It replaces your tailgate area with a storage box that folds away for full bed access.
The lid is a 10″ deep by full-bed-width fiberglass-reinforced polymer (FRP) panel on heavy-duty hinges. Inside is a sliding tray (included) for tools and small parts. The lid locks with the tailgate key, securing the contents.
Even better, the BAKBox 2 is weatherproof: solid FRP walls withstand water (and even serve as an ice chest!).
To use, you simply unlock and fold the box up against the cab for 100% bed access – rubber bumpers on the cab protect both.
It clamps on with no drilling and is rated to hold about 200 lbs when closed. This isn’t a flat tonneau cover, but for those needing a rear-bed secure storage solution, it complements BAK’s cover lineup.
Key Features
Real Use: BAKBox 2 owners use it as a mobile toolbox and cooler. Tradespeople stash tools inside with peace of mind that it’s locked and dry. Outdoor enthusiasts load it with drinks/ice or camping gear.
Many reviews highlight how sturdy it feels (solid panels won’t flex under weight) and the convenience of having a bed box that instantly folds away.
Installation takes about an hour. Users stress that while it’s an investment, the BAKBox 2 essentially transforms the truck bed into a secure lockbox, which is valuable for expensive equipment or even guns.
10. BAK Revolver X4ts Hard Roll-Up Cover (w/ T-Slot Rails)
The BAK Revolver X4ts is the ultimate heavy-duty roll-up cover with cargo management integration. It takes the proven X4s design and adds integrated T-slot channels along the side rails.
These T-slots allow you to mount accessories – bike carriers, kayak racks, ski racks, ski carriers, and more – directly to the bed rails above the cover. Construction is all top-tier: matte-black aluminum slats and vinyl (like the X4s), with the same patented rotational locking.
Weather protection is even better than before, thanks to full-perimeter seals and rugged corner caps.
One-handed opening is a breeze, and with the cover fully rolled up, you have unhindered access to the entire bed and any mounted cargo.
The whole assembly holds up to 400 lbs and comes with a 5-year warranty (cover) plus rail accessories sold separately.
Key Features
Fitment
Real Use: For truck owners who haul bikes or heavy gear, the X4ts is ideal. Cyclists mount bike racks on it, then fold the cover up when loading the bikes – a one-two combo. Contractors attach material carriers or a lumber ladder rack.
Feedback shows that owners love the sleek matte look and the fact they never have to remove the cover to use a rack.
Even with bikes on top, the cover locks and keeps cargo dry. In essence, the X4ts is BAK’s “Swiss Army knife”: it functions as a top-tier tonneau cover and a secure mounting platform all in one.
Buying Guide: Choosing the Right BAK Cover
Picking the best BAK cover depends on how you use your truck and which features matter most. Here are key factors to consider:
Material & Construction
All BAK covers (except the soft vinyl top on roll-ups) are rigid, either aluminum or FRP. Aluminum (MX4, G2) offers a balance of light weight and strength. FRP (F1, FiberMax) resists dents and weather. Hard surfaces make these covers lockable and strong.
Note: roll-up covers (Revolver X-series) combine aluminum slats with a vinyl layer – they’re still very durable, but use caution not to slash the vinyl top with sharp objects.
Bed Size & Truck Type
Measure your truck’s bed exactly. BAK covers come in sizes for different bed lengths (short, standard, long) and cab types. Ensure the model fits your specific make/year.
If your truck has a cargo track system or tie-down rails, be aware: some covers require it (CS, X4ts) while others need a plain rail (MX4/G2/F1/FiberMax). Always choose the model that matches your bed.
Type of Cover – Folding vs Roll-Up
BAK’s folding covers (MX4, G2, F1, FiberMax) consist of panels hinged together. They latch securely and give you the option to fold them forward.
This design keeps the bed low-profile but requires unfolding when you need full access. Roll-up covers (Revolver series) allow instant full-bed access – just pull the strap to roll up. They’re great for trucks that carry oversized cargo often.
Soft vinyl covers require a different style, but BAK focuses on hard covers. If you value quick access and one-handed use, consider a roll-up; for maximizing strength and security, a folding cover is ideal.
Security & Locking
Most BAK covers incorporate security. The folding covers (MX4, G2, F1) lock via your tailgate key – once the tailgate is locked, the cover can’t be opened. The Revolver X4/X4s also lock by the tailgate, with patented rails preventing prying.
The basic X2 model has no lock (tailgate must be open to roll). If you carry valuable gear, choose a cover with auto-locking design (MX4, Revolver X4s).
Ease of Use & Installation
BAK covers install with clamps only – no drilling – making DIY mounting easy. Depending on the model, you’ll need an hour or two to clamp, adjust, and tighten.
All covers include installation guides. Once installed: folding covers typically latch automatically; you pull a cable to unlatch and fold panels.
Roll-up covers need tailgate open (for X2) or can stay locked (X4s), then you pull a strap to roll. Ask yourself who will operate it: for one-person convenience, roll-ups excel. But for those who prefer the “flip-up” feel, folding covers work great.
Warranty & Support
BAK offers strong warranties. The MX4 and Revolver covers carry a 5-year warranty against defects. The G2 comes with about 3 years. FiberMax and F1 are around 2 years.
The BAKBox 2 toolbox has just 1 year. Be sure to register your cover with BAK after purchase to activate the warranty. Also look at retailer support (most BAK dealers can help with fit queries or returns).
Common Mistakes to Avoid:
- Wrong Fit: Never guess bed size. A cover too short or long won’t seal and will look odd. Measure from bulkhead to tailgate edge.
- Ignoring Rails: If your truck has integrated tie-down tracks, note which covers require them. For example, the CS and X4ts need track rails, while the MX4 and G2 cannot mount on trucks with C-channel decks.
- Budget vs Needs: Don’t overspend on features you’ll never use. If you only haul light loads, a midrange cover (G2 or FiberMax) may suffice. If you need heavy-duty, invest in an MX4, F1, or X4s.
- Forgetting the Tailgate: Remember whether the cover requires the tailgate down to operate (the old Revolver X2 and many retractable covers do). If you frequently open the tailgate with the cover on, ensure your choice doesn’t force you to remove or reposition it each time.
- Underestimating Weight: Though a cover can support some weight, avoid storing heavy items on top for long periods (even if rated) – it adds stress. Use tie-downs and racks properl
Before you buy, compare the top models above, check your truck’s bed specs, and decide which features matter most. Measure your bed, note any track systems, and think about how you use the truck daily. Choosing the right BAK cover means balancing budget, durability, and convenience. With the information above, you can confidently pick a BAK tonneau cover that fits your truck and lifestyle.
In summary, BAK leads with variety: from the rugged MX4 and F1 to versatile covers like the CS and Revolver X4s, there’s a BAK solution for every truck owner. Take advantage of the no-drill installation and solid warranties. When you’re ready to upgrade your bed, compare these models side-by-side and confirm compatibility with your truck. This guide should leave you informed and ready to choose the definitive BAK cover for your needs.
