• Five-position cam-style spring preload adjuster lets you dial in ride feel quickly without special tools.
• Built for longevity with straightforward construction that reduces maintenance and replacement cost.
• Multiple style options are available to match your bike's look, including different cover and spring/end-cap finishes.
• All shocks are measured center-of-eyelet to center-of-eyelet; confirm length before ordering or installation.

Installation notes: when fitting to '86-'15 XL models it may be necessary to modify or space the chain or belt guard for proper clearance. A shock slightly longer or shorter than stock can change head angle and steering response; always verify wheel travel and clearances to avoid contact with exhaust, chain or tire.

For heavy-load or frequent maximum-load use, consider the application recommendations and confirm fitment before installing different-length units. Made in the USA.
