QuadBoss 09-20 Yamaha YFZ450R Swingarm Repair Kit

QuadBoss is known for making tough parts for ATVs and UTVs. If you're rebuilding the swingarm on your 2009-2020 Yamaha YFZ450R or 2010-2011 YFZ450X, this repair kit has what you need to get it back in solid working order. It includes all the necessary components to properly rebuild the swingarm bearing assembly.

Inside this kit, you'll find needle bearing shafts made from 52100 bearing steel that's been hardened and precision ground for smooth operation and long life. The metal bushings are case-hardened and plated, which helps prevent wear and corrosion, keeping them in good shape even in rough conditions. QuadBoss also uses POM composite washer bearings instead of traditional thrust needle washers. These composite bearings offer an increased service life and are more resistant to water and dirt, which is a big plus for off-road riding.
