Notes:

Depending on model, your stock shock length is 11" to 13"
Shock lengths are measured fully extended, eyelet to eyelet on centers
A change in height at one end of the bike may require a change at the other
Changing ride height can potentially change the trail and mechanical trail
Heavy Duty shocks are recommended for bikes operated at or near the OEM maximum load rating over 50% of the time
Prior to purchasing shocks that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues to the swingarm, axle, frame, tire, fender, chain/belt and guard, and exhaust
