2020 Polaris RZR Turbo Pro XP Front Differential Rebuild Kit

This Polaris RZR Turbo Pro XP Premium Front Differential Rebuild Kit fits 2020 models. It gives you the upgraded internal parts needed when the front diff starts slipping, grinding, popping, or losing clean 4WD engagement.

Factory plastic sprague parts can become a weak link over time. So, this kit upgrades those key internals with metal components, fresh seals, a pinion shaft bearing, plates, hub parts, roller weights, and a retainer ring.

What This Kit Includes

• Pinion Shaft Oil Seal
• Internal Oil Seals (x2)
• Diff Housing O-Ring
• Pinion Shaft Bearing
• Upgraded Metal Sprague Cage
• Sprague Cage Roller Weights (x24)
• Differential Center Output Hub
• Upgraded Metal Cage Plate
• Upgraded Metal Armature Plate
• Differential Retainer Ring

Why Upgrade the Front Differential?

The front differential takes a beating when your Pro XP sees hard launches, rough terrain, and frequent 4WD use. Over time, worn sprague parts, tired seals, or loose internal components can lead to noise and poor front-end response.

This kit focuses on the parts that help restore stronger engagement. As a result, it is a smart choice for shops, mechanics, and RZR owners who want to replace common internal wear points before they cause more damage.
