Description

The Polaris RZR XP TURBO S is built for aggressive riding, and its front differential sees more abuse than most machines. When the original plastic sprague parts begin to wear, engagement gets sloppy and the front end loses the precision these models are known for. This Premium Front Differential Rebuild Kit replaces those weak points with upgraded metal components engineered for strength and long-term reliability.

The kit includes upgraded sprague components, fresh seals, new bearings, and reinforced internal plates—everything needed to restore crisp 4WD operation. Riders looking for additional drivetrain insight can explore our technical blog for maintenance tips and common diagnostic checks. If you want clarity on shipping steps, rebuild prep, or what to expect after ordering, our Help Center is a great resource.

Before you order, you can review coverage terms inside the warranty policy, or browse the FAQ section for quick answers on fitment. If you still need assistance, our team is available through the contact page.
