Features Nitrogen-charged steel monotube damper bodies with hard chrome-plated shafts Dual-rate progressive wound springs for a smooth, comfortable ride Adjustable spring preload Ride-height adjustable, /- 1/2" from size listed Black shocks feature black springs and damper bodies with black end caps/eyelets Mount with existing hardware Shocks shorter than OE length have reduced travel, this may affect the ride quality and handling of the motorcycle. Lowering the motorcycle will reduce ground and cornering clearance. 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. OE upper shock mount covers will not fit with these shocks. Not for use with rear lowering kits. May require custom mounting on models that have OEM-style offset mount shocks.
