Description

The Polaris RZR PRO XP puts serious load on its front differential, especially under hard acceleration and uneven traction. When the stock plastic sprague components begin to wear, engagement becomes inconsistent and the front end loses stability. This Premium Front Differential Master Rebuild Kit replaces those weak points with upgraded metal components engineered for long-term durability.

The kit includes new seals, fresh bearings, an upgraded metal sprague cage, roller weights, a reinforced output hub, and updated internal plates, all designed to restore crisp 4WD engagement and dependable drivetrain performance. Riders looking for additional drivetrain insight can browse our blog articles for technical tips and maintenance guidance.
