Product Details

When the transmission in your Polaris Scrambler or Sportsman starts to show its age, a full rebuild can bring it back to life. This QuadBoss Transmission Rebuild Kit is designed to give you all the essential components needed to get the job done. It includes a comprehensive set of ball bearings, needle bearings, tapered bearings, PTFE lined bearings, seals, and O-rings, all sourced from trusted manufacturers to ensure reliability. If your kit contains tapered bearings, you'll also find a selection of shims to help you achieve precise adjustments during the rebuild process.

This kit offers a direct O.E.M. replacement for your transmission's internal parts, providing a well-built solution at a more accessible price point than a full transmission replacement. The kit features high-quality ABEC 3 precision ball bearings, which are known for their smooth operation and durability. By replacing worn components with these quality parts, you can restore proper function and extend the life of your ATV's drivetrain. This kit is suitable for a range of Polaris models, including the Scrambler 850 and various Sportsman 850 and 1000 variants, making it a solid option for many riders looking to tackle a transmission overhaul.
