For 2003-09 Arctic Cat 500 Auto (also fits 07-08 Moose Tracker 4x4, some other 500cc 4x4 imports)
New version with complete roller assemblies
A new kit that contains complete drop in roller assemblies. This kit is designed to re-calibrate the shift pattern to help recover some of the losses from installing oversized tires. Bottom and midrange acceleration and performance are greatly improved. Also aids in performance when operating at higher elevations. This kit can be used with stock or oversized tires, however, when used with stock tires at low elevation it can cause a slight loss of top speed.
