The X-Rack's aluminum construction can accommodate spares from the OEM wheel to those sporting a lifted rig. Supporting a maximum diameter (tire) size of 38”, the X-Rack can accommodate nearly any size after-market tire & wheel. If you have questions or a larger size tire, call us! Our Engineering department will make sure the X-Rack can accommodate your spare. Jerk Engineered is the fusion of engineering and innovative design (patent pending) creating a system that does NOT piggy-back directly off of the van hinge. As such there is no longer the need to be limited to 180-degree hinges. The X-Rack tire carrier mounts securely to the innovative structural hinge brackets and only requires the drilling of a small (7/16” / 11mm) mounting hole in the door, and a slightly larger (11/16” / 17mm) hole hidden behind the interior trim panel. Included are both exterior and interior reinforcement plates to ensure the X-Rack is integrated with your van properly. The X-Rack, as with all JERK Engineered line of rear mounted systems, is engineered to serve you on the toughest terrain and harshest places you may travel. Be assured, the installation of this unit is simple for all to do. Note there is no need to change out hinges, ever! You keep your original hinges painted the color of your van!
