QuadBoss 10-13 Polaris RZR 4 800 (02) IRS Knuckle Only Rear Independent Suspension Repair Kit

When you're out on the trail and notice some play in your rear suspension, it might be time to address the independent suspension knuckle. This repair kit from QuadBoss is designed to get your Polaris vehicle back to feeling solid and responsive. It focuses specifically on the IRS knuckle, a key component for smooth operation over rough terrain.

Inside this kit, you'll find self-lubricating acetal nylon bushings. These are a big help for wear and overall performance, meaning they'll keep things moving smoothly for longer. The metal components in the kit are case hardened and plated, which adds a good layer of protection against wear and corrosion, especially important for off-road use. Being made in the USA is also a notable detail for this well-built kit.

This kit is a solid option for a range of Polaris RZR and Sportsman models from the mid-2000s to the mid-2010s. If you're looking to refresh your rear independent suspension, this repair kit addresses the knuckle assembly directly.
