Description

The Polaris RZR PRO XP demands a strong front differential to match its performance. When stock plastic sprague components begin to fail, 4WD engagement becomes inconsistent and reliability suffers. This Premium Front Differential Rebuild Kit replaces those weak links with upgraded metal internals designed for durability and consistent operation.

This rebuild kit features new seals, heavy-duty bearings, an upgraded metal sprague cage, roller weights, a reinforced output hub and upgraded plate components—everything required to restore reliable 4WD performance. To learn more about drivetrain upgrades and best practices, check out our performance blog.
