Want to upgrade your 2006+ (8") Boxxer Team or Race to a World Cup fork? Now you can with this upgrade kit. Get rid of that heavy spring and low-end Motion Control Damper. The kit includes a SoloAir top cap, internally honed left stanchion and SoloAir piston. If you have a Boxxer Race and also wish to upgrade your Motion Control damper to the Team/World Cup damper, please select that option before placing your order. This kit includes parts only and will require professional assembly. Your RockShox Boxxer should only be serviced by an authorized RockShox Service Provider. Please note that you are responsible for any additional service and labor charges encountered during the conversion of your fork.
