BAK Industries Tonneau Covers

Shop the BAK Industries bed cover lineup:  BAKFlip MX4 and Revolver X4S. Fitment guaranteed.

BAKFlip bed cover lineup

The BAKFlip bed cover lineup covers every hard folding use case BAK Industries builds for — from the budget-friendly G2 to the FRP-paneled F1. Truck Bed Barn stocks the full BAKFlip family: the BAKFlip MX4 (BAK's best-seller), the BAKFlip MX4 TS with integrated T-Slot rails for rack and accessory mounting, the entry-level BAKFlip G2, the FRP-topped BAKFlip FiberMax, and BAK's flagship BAKFlip F1.

For drivers who prefer a hard rolling cover instead of a folding one, BAK builds the Revolver line. Truck Bed Barn stocks both masters: the BAK Revolver X4s — a low-profile roll-up with vinyl-over-aluminum slats — and the BAK Revolver X4ts with integrated T-Slot rails for the same rack and accessory mounting the MX4 TS offers.

Whether you choose BAKFlip or Revolver, every BAK cover ships with the same engineering foundation: aircraft-grade aluminum (FRP on the FiberMax and F1), automatic latching that locks down when the tailgate closes, and weather sealing built around rubber perimeter gaskets plus an integrated drainage system.

BAK covers are sized for each truck make, model, year, and bed length — the wrong size will not seal. Run your truck through the fitment tool or message us before you order. Fitment is verified before every BAK cover ships.

How to choose your BAKFlip bed cover

  • If budget is the priorityBAKFlip G2 — aircraft-grade aluminum, 300 lb capacity, sub-$1,000 on most trucks.
  • If you want BAK's best-sellerBAKFlip MX4 — 22% stronger panels than the original, 400 lb capacity, matte black finish.
  • If you run racks or carriersBAKFlip MX4 TS or BAK Revolver X4ts — both add integrated T-Slot rails on both sides for crossbars, bike mounts, and overlanding gear.
  • If you want dent-resistant panelsBAKFlip FiberMax — fiberglass-reinforced polymer top panels over aluminum, better impact resistance and cooler in heat.
  • If you want a hard rolling cover instead of foldingBAK Revolver X4s or X4ts — vinyl-over-aluminum slats that roll up to the cab and lock at any position along the rail.
  • If you want the flagshipBAKFlip F1 — FRP top panels with a foam core, 400 lb capacity, BAK's longest warranty.

BAKFlip FAQ

Is the BAKFlip cover good?
Yes. The BAKFlip family is one of the most established hard folding tonneau lines on the market. The MX4 is BAK's best-seller — aluminum panels, automatic latching, 400 lb capacity. The G2 is the budget-friendly entry, the F1 is the flagship with FRP construction. Fitment is verified before every order ships.
What is the difference between BAKFlip and BAK Revolver?
BAKFlip is BAK's hard folding line — rigid aluminum or FRP panels that fold flat against the cab for full bed access. BAK Revolver is the hard rolling line — vinyl-bonded aluminum slats that roll up and lock into a canister at the cab end. Folding gives faster full-bed access; rolling locks at every intermediate position for partial-open use. Both ship with automatic latching and weather sealing. Truck Bed Barn stocks the full lineup of both.
What is the difference between the BAKFlip G2 and MX4?
Both share the same hard folding design and automatic latching. The MX4 is the upgrade tier — panels are 22% stronger, the finish is textured matte black instead of semi-gloss, weight rating jumps from 300 to 400 lbs, weather sealing is improved, and the warranty is longer. The G2 is the value pick at roughly $100 less on most trucks.
Which BAK cover is best for racks or accessories?
Either the BAKFlip MX4 TS (hard folding) or the BAK Revolver X4ts (hard roll-up). Both add integrated T-Slot rails running along both sides, compatible with most major rack systems (Yakima, Thule, Rhino-Rack) for crossbars, bike mounts, kayak carriers, or overlanding gear.
Are BAK covers waterproof?
Water-resistant rather than fully waterproof — the same answer applies to every folding or rolling tonneau on the market. BAK covers use rubber perimeter seals, rounded hinges (or slat seals on the Revolver), and an integrated drainage system to route water out of the bed. For rain, snow, and car washes, cargo stays dry.
How do you install a BAK cover?
Every BAK cover uses a no-drill clamp-on mounting system. Mounting rails clamp directly to the bed rails and the cover (folding panels or rolling slats) sets into place. Most trucks take 30 to 60 minutes with basic hand tools, one person, no permanent modifications.
How long do BAK covers last?
All BAK covers ship with the full factory warranty. Real-world lifespan typically exceeds the warranty period — many customers run the same cover across multiple trucks. Warranty details vary by model; check the individual product page for the current terms.
Will a BAK cover fit my truck?
BAK covers are sized for each truck make, model, year, and bed length — they are not universal. The wrong size will not seal. Run your truck through the fitment tool or message us before you order. Fitment is verified before every order ships.
