Frequently Asked Questions

Can I adjust the preload myself?

Yes — the 5-position cam-style adjuster requires no special tools. Turn to dial in your preferred ride height and stiffness.

What's the difference between standard and heavy-duty springs?

Standard springs suit lighter riders; heavy-duty springs provide stiffer support for heavier riders or two-up riding.

Will these improve my stock suspension?

Yes. The nitrogen-charged damping and progressive valving deliver smoother, more consistent handling compared to factory shocks.

Do the show chrome covers come installed?

Optional — show chrome covers are available on select Harley models and must be specified at order.
