Retrax PowertraxONE XR T-70484


  • The integrated Trax Rail System works well with most T-slot rack accessories from Rhino Rack, Yakima, Thule, and many more.
  • Utilizing a remote keyfob, this retractable pickup bed cover opens and closes at the touch of a button. Wireless operation allows it to easily open and close, and an electromagnetic brake allows it to lock in any position along the rail.
  • The patented low-profile design incorporates a front cover that is flush with the truck bed cover, which streamlines the overall appearance and provides a firm, dependable seal to help to keep the truck bed dry.
  • Sealed ball-bearing rollers mounted onto the aluminum support beams allow the PowertraxONE XR truck bed cover to retract or close effortlessly without the use of springs or any kind of mechanism no moving parts to jam, freeze or fail.
  • Constructed from a one-piece sheet of polycarbonate that is engineered to retract without joints or hinges that can trap dust, wear out or freeze.


Presenting the XR Series, a fusion of the PowertraxONE MX and the integrated Trax Rail System, enabling distinctive and personalized modifications atop your tonneau cover. Within our Polycarbonate Series range, the PowertraxONE XR electric retractable truck bed cover stands out. The XR Series enhances cargo space utilization whether the cover is open or closed, delivering unparalleled flexibility in cargo organization.

The Trax Rail System seamlessly interfaces with a wide array of T-slot accessories, including renowned brands like Rhino-Rack, Yakima, and Thule, among others, opening up limitless opportunities for customization. When the Trax Rail System is paired with accessories, it effectively doubles the available cargo capacity. This innovative technology liberates the hitch, enabling the mounting of bicycles, coolers, outdoor equipment, and more onto the bed cover. The combination of the Trax Rail system and T-slot accessories is the key. For a personalized fit, consult our Accessory Compatibility Chart. (Accessories available for separate purchase.)
