Frequently Asked Questions

Can I adjust these shocks after installation?

Yes — three-way adjustability lets you dial preload, compression damping, and rebound independently without tools or special knowledge.

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

12.5" maintains stock ride height on Dyna and Sportster. 14" raises the rear for a classic tall-shock look and increased ground clearance.

Will the 14" shocks fit my 2004-2013 Sportster?

They will fit, but 2004-2013 Sportster models may require relocating the rear master cylinder for proper clearance.

What is Speed Adaptive Valving?

SAV technology adjusts damping based on suspension speed, providing plush ride quality at low speeds and firm support under hard braking or acceleration.
