That extended wheelbase gives you more stability and clearance for larger tires, and the trailing arms come complete with all bearings. Because of that longer wheelbase, these portals require Rhino or Rhino 2.0 axles. They™re built for the high articulation you get with a longer wheelbase, and their chromoly shaft and CV joints make them super strong and durable for any riding application. Complete the Package with a Frame Stiffener Portals and monster tires are fun, but they can place additional stress on your machine™s frame. To make your suspension bulletproof, we recommend adding a SuperATV Frame Stiffener when you install your new Can-Am portals!
