Features to know about

Low-Profile Cargo Carrying: 56-1/8" Aluminum Crossbars Above the Tonneau Cover

These mid-height crossbars give you a solid platform for hauling gear right above your ReTrax XR tonneau cover. Each bar measures 56-1/8" long, 3-1/2" wide, and 1" tall, providing plenty of width for kayaks, boards, or camping gear without adding too much height. The setup keeps your load low and centered for better aerodynamics while letting the tonneau cover open and close normally.

Built for Tough Trips: Rugged Aluminum with Black Powder Coat Finish

The rack is made of durable aluminum and finished with a black powder coat that’s completely rustproof. It’s designed for outdoor use and tested in extreme conditions, so it stands up to rough roads, heavy weather, and year-round use without corroding or fading. That finish also helps protect against scratches and everyday wear.

Flexible Mounting Options: Integrated Top and Bottom T-Slots

Integrated T-slots on both the top and bottom of the crossbars make it easy to mount a wide range of Front Runner accessories. You can secure tie-downs, brackets, or cargo platforms wherever you need them. This channel system gives you the flexibility to set up your rack exactly how you want for work gear or weekend trips.

Simple, No-Drill Fit: Mounts to Existing ReTrax XR Rails

The fixed legs bolt directly into the existing ReTrax XR tonneau cover rails, so there’s no drilling or modification required. Once installed, the crossbars sit above the truck bed rails for easy access to your gear. It’s a clean, straightforward setup that makes use of the rails you already have while keeping your load bed free for everyday hauling.
