LEAD TIME IS 4-6 WEEKS

These 3″ tall risers can be attached to a Retrax XR or DiamondBack bed cover, allowing you to safely transport rooftop tents, bikes, storage boxes, and just about anything else you can think of on your next adventure. The Retrax XR kit will fit many other similar extrusion rail systems. If you are curious about fitment with other setups, please reach out and we’ll advise the best we can. The DiamondBack kit attaches directly to the HD or SE factory cleats, and does not require drilling any new holes into the cover. If you’d like to install at other locations, you may do so, but drilling will be required.

It is equipped with the new upTOP VL (Variable Length) Crossbar, which allows you to select the perfect width for your truck from as little as 50 Inches to an industry-leading 72 Inches without compromising the crossbar’s strength and rigidity. The same bar can be run flush or extended, depending on your setup or use case. These will fit any standard truck bed.

Quick, easy assembly and installation without modifying or drilling into your truck bed. Use the drop-down menu to select your application.
