Installation Notes

Longer than stock shocks may require modification — check your bike before ordering. We recommend the 13-1/2" shock for most applications, but the final choice is yours. If you choose a length and are unhappy with it you can purchase parts to modify the length yourself.

• Touring 2013–2017: 14-1/2" or longer shocks cause the swingarm to hit the transmission.
• All other Touring models: swingarm usually hits the transmission with shocks longer than 15-1/2".
• All Nightster models: shocks longer than 15" cause the swingarm to hit the gas tank; longer than 14" and the stock exhaust hits the shock bolt.
• Dyna models: shocks longer than 13-1/2" will allow the chain to drag on the case.
