Frequently Asked Questions

Can I adjust these shocks myself?

Yes — preload, compression, and rebound adjusters are all externally accessible. No special tools needed for basic tuning.

Do 2004-2013 Sportsters fit the 14" shocks without modifications?

The 14" tall shocks may require relocation of the rear master cylinder on 2004-2013 Sportsters. The 12.5" stock length shocks fit without modification.

What is Speed Adaptive Valving?

SAV automatically adjusts damping based on suspension speed, providing consistent performance across all riding conditions from slow cruising to hard cornering.

What's the difference between the 12.5" and 14" options?

12.5" maintains stock ride height, while 14" raises the rear for a lifted club-style or lowrider stance.

Are these street-legal?

Yes — these are suspension components designed for street use on Dyna and Sportster models.
