Easily accessible adjustment knobs for high-speed and low-speed compression damping 0.4” adjustable height eyelet High-pressure gas monotube Captured designed jounce bumper for smooth and controlled bottoming Piggybacking reservoir Aluminum body Linear rate coil spring Deflective disc damping All shocks are measured center-of-eyelet to center-of-eyelet. A shock which is slightly longer than stock may alter the head angle slightly and provide somewhat quicker steering. 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. Los amortiguadores más largos que stock en FXDB/FXDWG puede causar que el eje/amortiguador/basculante entre en contacto con el sistema de escape y por tanto deben comprobarse holguras adecuadamente.
