Review 4XPRO Polaris Rear Differential Seal Kit fits SPORTSMAN 400 500 2001–2010

Introducing the 4xPro 220-319.01 rear differential seal kit, specifically designed for Polaris Sportsman 400 and 500 models produced between 2001 and 2003, as well as the 2010 version. This kit is an essential upgrade for those seeking superior performance and durability from their off-road vehicle.

Each seal in this comprehensive kit is meticulously engineered to provide a perfect fit and function. The seals are manufactured using high-quality materials that are resistant to wear and tear, ensuring a long-lasting solution for your Sportsman. The kit includes all necessary seals required for the rear differential, including the pinion seal, side seals, and axle shaft seals.

The pinion seal is a critical component that prevents oil from leaking out of the differential. The 4xPro pinion seal is designed to provide an effective barrier against oil loss, even in the most demanding off-road conditions. The side seals, on the other hand, are responsible for maintaining the differential fluid within the housing. These seals are designed to be flexible yet durable, ensuring a tight seal that prevents leaks while allowing for proper differential movement.

Lastly, the axle shaft seals are an essential component that keeps differential fluid contained within the housing and prevents it from coming into contact with the elements. The 4xPro axle shaft seals offer exceptional sealing performance, ensuring that your Sportsman's differential remains well-lubricated and protected from the effects of the environment.

Installing the 4xPro 220-319.01 seal kit is a straightforward process. Each seal comes with clear installation instructions, ensuring that even the most novice DIYer can complete the job with confidence. Furthermore, the kit includes all necessary hardware, making it a one-stop solution for all your rear differential seal needs.

By providing a perfect fit and superior sealing performance, you can enjoy peace of mind knowing that your differential is well-protected against leaks and damage.
