Description

The Polaris RZR RS1 delivers sharp handling and fast response, which puts constant stress on the front differential. As seals wear, the diff can begin to leak or draw in contamination. To prevent this, our Premium Front Differential Seal Kit replaces the original seals with upgraded components designed for strength and long-term reliability.

This kit includes new oil seals and a fresh housing O-ring to help maintain proper lubrication and protect the differential from early wear. As a result, the RS1 stays smoother and more consistent during aggressive riding. For additional drivetrain tips and maintenance advice, you can browse our REV6 blog.

Before ordering, you can review coverage inside our warranty policy. If you need help with shipping steps or installation prep, the Help Center lays out the process clearly. For quick fitment answers, check the FAQ page, or reach our team anytime through the contact page.
