2020 Polaris RZR Turbo Pro XP Front Differential Master Rebuild Kit

This Polaris RZR Turbo Pro XP Premium Front Differential Master Rebuild Kit fits 2020 models. It gives you the internal parts needed when the front diff starts grinding, slipping, binding, or losing clean four-wheel-drive engagement.

Instead of only replacing a few wear parts, this master kit refreshes the front differential with upgraded metal sprague components, seals, bearings, gears, plates, hub parts, and hardware. As a result, it is a strong fit for shops, mechanics, and RZR owners who want a more complete front diff repair.

• Pinion Shaft Oil Seal
• (2) Internal Oil Seals
• Diff Housing O-Ring
• Pinion Shaft Bearing
• Upgraded Metal Sprague Cage
• (24) Sprague Cage Roller Weights
• Differential Center Output Hub

Built to Replace Common Front Diff Weak Points

The factory front differential can take a beating from hard launches, rough terrain, and aggressive 4WD use. Over time, worn sprague parts, tired seals, bad bearings, or damaged gears can cause noise, poor engagement, and weak front-end response.

This kit replaces the OEM plastic sprague-style parts with upgraded metal components. Plus, the included input pinion shaft, main pinion gear, armature plate, cage plate, center output hub, seals, bearings, and hardware help cover more of the internal rebuild.
