• Before purchasing or attempting to install shocks that are different than the OEM length, confirm that your wheel travel can be altered without causing clearance issues such as swingarm/axle to exhaust contact as well as chain/belt guard or tire contact.

Please confirm your exact model and year in the fitment chart before ordering.
