QuadBoss 14-16 Polaris ACE 325 IRS Knuckle Only Rear Independent Suspension Repair Kit

This rear independent suspension (IRS) knuckle repair kit from QuadBoss is designed to get your Polaris back on the trail with solid performance. It specifically addresses the knuckle component of the rear IRS system, which is crucial for proper wheel alignment and handling. The kit includes self-lubricating acetal nylon bushings, a material chosen for its ability to reduce friction and wear, leading to better performance and longevity for your suspension components.

Beyond the nylon bushings, the metal components in this kit are case hardened and plated. This treatment significantly increases their resistance to wear and corrosion, ensuring they hold up under the demanding conditions off-road vehicles often face. Being made in the USA, you can expect a well-built part that’s ready to handle the rigors of your Polaris ACE or Ranger, fitting a range of models like the Polaris ACE 500 or the Ranger 900 XP.
