QuadBoss 01-05 Yamaha YFM660R Raptor Swingarm Repair Kit

If you're rebuilding the swingarm on your 2001-2005 Yamaha YFM660R Raptor, this QuadBoss repair kit has the parts you need to get the job done right. A worn swingarm bearing assembly can lead to sloppy handling and premature wear on other suspension components, so replacing these parts is key to restoring your Raptor's performance.

This kit includes needle bearing shafts made from 52100 bearing steel, which is hardened and precision ground for durability. The metal bushings are case-hardened and plated to resist wear and corrosion, helping them stand up to the elements. You'll also find POM composite washer bearings that replace traditional thrust needle washers, offering a longer service life and better protection against water and dirt intrusion.
