Replace the factory spherical bearing that is prone to cracking and breaking, which could leave you stranded on the trails. Inspect your OEM bearings, especially the lower ones, before and after each ride. We have made replacing these with a much stronger and affordable upgrade super simple. Using F.K. chromoly 5/8" uniballs, these will extend the service life of your Fox shock by thousands of miles. 304 stainless steel, precision machined misalignment spacers offer a much larger contact patch and mating surface, making cracking and breaking a thing of the past. We keep the dirt and debris out with the neoprene seals provided. S3 Power Sports HD Fox Shock Uniball Rebuild Kit comes with everything you need and installs in minutes with no modification required. A much needed, cost effective, and simple upgrade over the OEM spherical bearings on your Can-Am!
