Important to know
Shocks slightly longer than stock may alter the head angle slightly, providing quicker steering. Shocks slightly shorter than stock may alter the head angle and provide slower steering. Before purchasing or attempting to install shocks different than the OEM length, confirm your wheel travel can be altered without causing clearance issues, such as swingarm/axle to exhaust contact and chain/belt guard or tire contact.
