Features to know about

Haul More Gear Without Losing Bed Space: Mid-Height Over-Bed Design

This mid-height rack keeps your gear safely above the truck bed and ReTrax XR tonneau cover, giving you overhead storage without blocking access to the bed itself. The fixed legs sit just above the bed rails, so you can easily reach tools or cargo underneath. Because the crossbars sit below cab height, they also cut down wind drag for smoother, quieter travel.

Built for the Outdoors: Durable Aluminum with Black Powder Coat Finish

The rack’s aluminum construction is strong yet lightweight, and the black powder coat finish makes it rustproof. It’s built and tested for outdoor conditions, from rough roads to wet weather, so you can leave it on year-round without worrying about corrosion or damage. That means more time using it and less time maintaining it.

Mount What You Need: Integrated T-Slots for Accessories

Each of the three 62" long crossbars has T-slots along the top and bottom, giving you flexible mounting points for a wide range of Front Runner accessories (sold separately). Whether you’re carrying kayaks, recovery tracks, or a rooftop tent, you can position and secure your gear exactly how you want it.

Easy Setup: Installs on ReTrax XR Rails with No Drilling

The legs mount directly into the existing ReTrax XR tonneau cover rails, so there’s no drilling or permanent modification needed. The low-profile setup fits cleanly into the rails and keeps your truck bed’s normal load-carrying function and tailgate use intact. With a total system weight of just 19.84 lbs, it’s a simple, sturdy upgrade that’s easy to handle and install.
