The five-position cam-style spring load preload adjuster makes it easy to dial in your ride for comfort or control.

Some or all shocks listed are approved for road use; refer to the most recent certificate for current listing.

Multiple style options are available, including full show-chrome or black covers, or chrome or black springs and end caps.

All shocks are measured center-of-eyelet to center-of-eyelet, and a shock slightly longer or shorter than stock may alter head angle and steering response.

Heavy duty applications are recommended for bikes that operate at or near the manufacturer's maximum load rating over 50% of the time.

Before purchasing or attempting to install shocks of a different OEM length, confirm wheel travel and clearances such as swingarm/axle to exhaust contact, chain/belt guard, and tire clearance.
