• Five-position cam style spring preload adjuster for quick tuning of ride stiffness.
• Designed with longevity and serviceability in mind — a cost-effective suspension improvement.
• Some or all shocks listed are approved for road use; refer to the most recent certificate for current listings.
• Multiple style options are available, including covers and spring/end cap finishes.

Before purchasing or installing shocks that differ from OEM length, confirm wheel travel and clearance to avoid contact with swingarm, exhaust, chain/belt guard, or tire. On '86-'15 XL models it may be necessary to modify or space the chain/belt guard for proper clearance. A slightly longer shock can quicken steering; a slightly shorter shock can slow steering.

Recommended for heavy duty applications when the bike is operated near the manufacturer's maximum load rating more than 50% of the time. All shocks are measured center-of-eyelet to center-of-eyelet.

Made in the USA. For fitment questions or installation guidance, consult a qualified technician or the most recent fitment documentation. 🇺🇸
