Ram 1500 Bed Cap – Premium Truck Caps for Your Ram
Our CX Series bed cap transforms your Ram 1500 into a secure, weather-tight cargo hauler without sacrificing the rugged looks that drew you to your truck in the first place. We engineer every cap specifically for Ram 1500 bed dimensions—whether you're running a 5'7", 6'4", or 8' box—so the fit is factory-tight from day one.
The cap's one-piece fiberglass construction eliminates the rattles and flex you get with bolt-together designs, while our OEM-matched paint process ensures the finish ages with your truck's paint instead of fading or chalking after a season in the sun. Reinforced roof supports handle full ladder racks and 300-pound distributed loads, making this the last cap you'll buy for your Ram.
Built for your Ram 1500
Fiberglass Construction & Paint Match
We mold every shell from a single piece of marine-grade fiberglass reinforced with structural ribs that mirror the stress points in your Ram’s bed. That means no seams to separate, no panels to warp, and no aluminum trim pieces that corrode where dissimilar metals meet.
The gelcoat surface goes through a six-stage cure before we apply urethane basecoat and clearcoat in the exact PPG or BASF formula your truck left the factory wearing. Whether you’re matching Granite Crystal or Flame Red, the cap arrives color-sanded and buffed to the same orange-peel texture as your cab—so the only way someone knows it’s aftermarket is if you tell them.
Window Configurations & Ventilation
Every CX Series Ram 1500 bed cap ships standard with tinted sliding side windows that lock independently and include pop-out screens for airflow without letting in rain or trail dust. The sliders run on stainless tracks—no plastic rollers to crack in January—and the glass is the same DOT-rated safety glass your truck’s rear window uses.
Rear Door Options
We offer three rear configurations: a solid rear panel for maximum security, a sliding rear window that mirrors the sides, or a full walk-in rear door with a gas strut and paddle handle. The walk-in door is frameless—the entire rear panel lifts on hidden hinges—so you can load plywood, ladders, or an ATV ramp without the center post that splits every other cap’s rear opening in half.
Mounting & Bed Compatibility
The cap mates to your Ram’s bed rail through a continuous C-channel clamp system—twelve points of contact instead of the four or six bolts other brands use. That distributes load evenly and prevents the stress cracks that show up around bolt holes after a year of washboard roads.
We account for Ram’s spray-in bedliner lips, so the clamps grip the rail itself rather than relying on friction against textured plastic. The rubber bulb seal compresses just enough to stay watertight through bed flex without creating the binding that makes removal a two-person job. The same hardware kit works across 2009–2024 Ram 1500 platforms, including the new Hurricane inline-six trucks, because we update the mold every model year to track Ram’s dimensional changes.

Ram 1500 Bed Cap Questions
Yes—our clamp system is designed to grip the bed rail itself, not the liner surface. The C-channel clamps slide beneath the liner lip and compress the bulb seal against the rail's top edge, so the liner actually helps create a tighter seal by filling any gaps between the rail and the clamp.
We provide spacer shims if your liner is thicker than 1/8", which keeps the clamp tension even along the entire rail. Most Line-X, Rhino, and Speedliner applications don't require spacers, but we include them in every kit just in case.
Installation is straightforward if you have a second person to help lift the cap onto the bed—it weighs about 180 pounds, so it's not a solo job. The clamps thread onto pre-installed studs in the cap's lower rail, and you tighten them in a star pattern like lug nuts to ensure even compression.
Most owners complete installation in under an hour using basic hand tools. That said, our dealer network offers installation, paint-match verification, and key-alike service, so if you'd rather have professionals handle the initial fit and seal check, we recommend going that route—especially if you're also adding a ladder rack or interior shelving at the same time.
Every cap is painted to order using your truck's paint code, which you'll find on the driver's door jamb sticker. When you order through an A.R.E. dealer, they'll verify the code and submit it with your configuration so our paint shop can mix the exact basecoat and clearcoat formulas.
We maintain PPG and BASF mixing data for every Ram color from 2009 forward, including limited-production shades like Ignition Orange and B5 Blue. The cap ships color-sanded and buffed to match your truck's orange-peel texture, so if your Ram is three years old with some clear-coat weathering, let the dealer know—we can adjust the buff level to blend with aged paint instead of looking showroom-fresh next to a faded cab.
The terms are often used interchangeably, but a bed cap typically refers to a fiberglass or aluminum topper that sits flush with the bed rails and focuses on cargo security and weather protection. A camper shell usually implies taller sidewalls, interior amenities like sleeping platforms, and sometimes pass-through access from the cab.
Our CX Series is technically a bed cap—it follows the roofline of your Ram's cab and prioritizes aerodynamics and a factory-integrated look. If you need standing height or plan to build out a sleeping setup, you'd want our taller DCU or camper shell models instead.
In most real-world driving, a properly designed cap improves aerodynamics and reduces drag compared to an open bed, especially at highway speeds. Owners typically report a 0.5 to 1 MPG improvement on highway trips once the cap smooths airflow over the bed.
City mileage stays about the same because you're adding 180 pounds to the truck, which offsets any aero benefit in stop-and-go traffic. The net effect depends on your driving mix—if you're doing a lot of 70 MPH interstate runs, you'll see a measurable improvement; if it's mostly around-town errands, the difference is negligible.
No—a bed cap replaces a tonneau cover entirely because both mount to the bed rails. If you currently have an A.R.E. tonneau and want to upgrade to a cap, we offer a conversion kit that reuses some of the mounting hardware, but the tonneau itself comes off.
Some owners keep their old tonneau as a summer option and swap the cap on in fall for winter weather protection. The CX clamp system makes removal and reinstallation simple enough that seasonal swapping is realistic if you have a place to store whichever component isn't in use.
Yes—our structural warranty against delamination, cracking, and gelcoat failure stays with the cap, not the original purchaser. If you sell your Ram with the cap installed, the new owner gets the remaining coverage as long as they can provide proof of original purchase date.
The warranty covers material defects and workmanship but excludes damage from accidents, improper modification, or neglect. We've honored claims on ten-year-old caps that developed stress cracks due to manufacturing issues, so the lifetime term isn't just marketing—we stand behind the build quality for as long as you own the product.
