The AA clutch kit is designed to increase performance, decrease belt temps and provide better throttle response. There are two kits available: 1. Performance setup and High load setup.
The performance setup I optimized for the majority of Turbo S owners who are happy with stock size tires and are looking to improve the efficiency of power delivery to the wheels.
A high load setup is for those riders that jump up in tire size by 2-3" or run a very heavy tire/wheel setup. If you're running a larger tire this setup will optimize the pulling power you need and add that performance back into your machine.
