The Polaris 2204107 is a genuine OEM outer rear CV joint boot, also known as a rubber cover, specifically designed to protect the constant velocity (CV) joint on the rear axle. This essential component prevents contaminants like dirt, water, and debris from entering the joint, ensuring its longevity and smooth operation. Manufactured to Polaris's stringent quality standards, this boot provides a precise fit and durable performance for maintaining the drivetrain integrity of a wide range of Polaris ATVs and UTVs, including popular RANGER, RZR, SPORTSMAN, GENERAL, ACE, and SCRAMBLER models.
