The Norton Racing Perfect Shift Arm kit contains a universal shift arm and eight different offset lengths to set the shift arm position exactly where you want it to be. This shit kit will allow you to adjust the clearance and optimized the shift angle. In my opinion, this modification is a must if you installed an aftermarket Quick Shifter and/or upgraded your rearset.
Before installing the Perfect Shift Arm kit, my shift knuckle was at the very edge of the spline, and the module of my HM QuickShifter was almost touching my rearset mounting plate. This kit from Norton Racing allowed me to properly adjust the knuckle, which is now fully seated on the spline. Additionally, I was able to choose a spacer that extended the distance between the shift arm and the rose join to the optimal position. As a result, my shift rod is now perfectly perpendicular to the bike, which provides much smoother shifting.
