BAKFlip FiberMax Hard Folding Tonneau Cover for 2019-2026 Ram 1500 without RamBox (6'4" Bed)

The DT Ram 1500 with the 6'4" bed is the version people buy when the truck has to be both a daily and a work vehicle, and it is a bed that gets loaded around: ladders in and out, material sliding along the floor, tools coming and going. FRP top panels are the right answer to that. Fiberglass-reinforced polymer takes abrasion and impact better than vinyl or a plain skin, resists cutting when the truck is left somewhere unattended, and stays UV stable so the finish keeps matching the rest of the truck. The patented rail carries 300 lb evenly distributed, and it all clamps on with no drilling.

What's Included:

• BAKFlip FiberMax hard folding tonneau cover, pre-assembled
• Two clamp-on mounting rails
• Clamp set and hardware kit
• Nylon buckle straps and integrated prop rods
• BAKFlip hard-folding install guide

Features

Fiberglass-Reinforced Polymer Panels
The FiberMax leads with its panels. Fiberglass-reinforced polymer tops handle impact, abrasion, and temperature swings better than vinyl or a plain aluminum skin, and they sit on an aluminum substructure that spreads the load. Closed, the cover carries 300 lb evenly distributed, which is enough for boards, plywood, or a flat load laid across the bed.

UV Resistant, So the Finish Stays Put
The outer panels are highly UV resistant. That matters if your truck lives outside: the textured gloss-black finish holds its color and depth through years of sun instead of chalking and fading the way an untreated surface does.

Cut and Puncture Resistant Where a Soft Cover Is Not
A knife goes through a soft tonneau in a second. The FiberMax panels are rigid FRP, so they resist cutting and puncturing and turn away most casual break-in attempts. Latch the cover down over a closed tailgate and what is in the bed stays out of sight and out of reach.

Sealed Rails and an Internal Water Channel
EPDM rubber outer rail seals and rounded hinges block most water right at the rail. What gets past runs into an internal channel built into the rails, down the tracks, and out the drain hoses. The FiberMax uses a conventional tailgate seal, so close the tailgate first and the cover second for the best water resistance.

Patented Rail With a Load-Bearing Flange
The rail is the part most covers skimp on. BAK's patented design carries the panels on a load-bearing flange that runs the length of the bed rather than at a handful of points, which is what makes the 300 lb evenly distributed rating honest and keeps the panels from flexing between supports.

Buckle Straps, Prop Rods, and No Drilling
Reach under the cover with the tailgate open, pull the release cables, and fold it forward. Nylon buckle straps hold the two-thirds-open position, and the integrated prop rods hold it folded against the cab for full bed access. Installation clamps on with the included hardware in under an hour, no drilling or trimming, and the cover is assembled in Missouri and backed for 3 years.

The BAKFlip FiberMax arrives pre-assembled with every clamp, fastener, and instruction sheet in the box. Nothing is cut, drilled, or modified on the truck. Work through the included BAKFlip hard-folding install guide for clamp placement, and remember the FiberMax uses a conventional tailgate seal, so the tailgate closes before the cover.
