QuadBoss 99-00 Honda TRX400EX FourTrax Swingarm Repair Kit

If you're rebuilding the swingarm on your 1999-2008 Honda TRX400EX Sportrax, this QuadBoss repair kit has the parts you need to get it back in working order. A worn-out swingarm bearing assembly can lead to sloppy handling and premature wear on other suspension components, so addressing it with the right parts is key to maintaining your ATV's performance.

This kit includes needle bearing shafts made from 52100 bearing steel that's been hardened and precision ground for a solid foundation. The metal bushings are case-hardened and plated, which helps them resist wear and corrosion, keeping them working longer. QuadBoss also uses POM composite washer bearings instead of traditional thrust needle washers. These composite bearings offer a longer service life and are more resistant to water and dirt contamination, which is a big plus for off-road riding.
