Mule Back XL

The Mule Back System is the exceedingly versatile and innovative way for you to configure the critical gear you want to travel with. Mount almost anything to the Mule Back: Bikes, skis, cargo boxes, fuel cans, the list only ends when you are through. Additionally, with our FTSN  (fixed thread single nut) design, items can be quickly switched based on the trip you will be taking! The MBXL Series is an all aluminum design which is light weight without compromising strength. Its design gives you a multitude of mounting options for you to find your perfect v gear configuration. 

We have applied engineering design to the geometry and strength calculations, and with an innovative design (patent pending) have created a system that does not piggy-back off of the hinges of the van, therefore there is no need to force the use of only 180-degree hinges to mount your rear systems to your van any longer.
