A shock which is slightly shorter than stock may alter the head angle slightly and provide somewhat slower steering.
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.
NOTE: 12-5/8" stock length shock on 1993-2007 FXD/FXDL /FXDWG. Installing 11.50" or shorter shocks on the FXDWG requires modifications to the fender. | Shocks longer than stock length on FXDB/FXDWG may cause Axle/Shock/Swingarm to contact exhaust system and clearances should be checked.
