Frequently Asked Questions
What's the difference between Standard and Heavy-Duty spring rates?
Both offer 0.8–1 in ride height adjustments via the 2:1 motion ratio. Heavy-Duty handles heavier loads or two-up riding; Standard suits solo or lighter applications.
Can I adjust preload while riding?
The R.A.P. knob allows hand adjustment of preload without tools, but we recommend adjusting before your ride for safety.
How do I set the rebound damping?
The 5-position rotatable adjuster lets you dial rebound from soft to stiff. Start in the middle and adjust based on how the bike handles bumps and dips.
What shock length should I order?
Longer lengths (13.1–13.5 in) raise ride height; shorter lengths (12.2–12.6 in) lower it. Consult the Progressive chart or your dealer for your weight and ride preference.
Are these hand-built and tested?
Yes — every shock is hand-built, tuned, and dyno-tested at the factory before shipment.
