All Balls Racing – Suspension Rebuild Packages, including rear independent suspension packages for the 2019 Can-Am Outlander 450 6x6, the 04-05 Outlander 330, the 14-16 Polaris ACE 325, the 12-13 Polaris Sportsman 550, the 07-11 Yamaha YFM350 Grizzly IRS, the 09-22 Suzuki LT-A500X and the 03-05 Honda TRX650 Rincon, most listed as two kits required per vehicle. Each package gathers the bearings, bushings, seals and pivot hardware for one side of an IRS rear end into a single box, which is how the job should be done: replace everything in the linkage at once so you are not chasing a fresh clunk two rides later. Worn a-arm and knuckle bushings show up as deflection under load, uneven tire wear and steering that wanders when you hit a rut at speed. Rebuilt with these ATV suspension rebuild kits, the rear end tracks straight, holds alignment and puts power down predictably in ruts and off-camber. Grease the pivots on schedule afterward and the rebuild will outlast the tires on the machine. Order two kits for a full rear axle unless noted. Give us your year and model and we will confirm quantity and correct fitment before you order.
