Frequently Asked Questions
Can I adjust the preload myself?
Yes. The 5-position cam-style adjuster is rider-adjustable — no tools needed to change preload for different loads or riding preferences.
What's the difference between Progressive and Heavy-Duty spring rates?
Progressive springs use a rising rate that feels softer initially but firms up under load. Heavy-Duty springs are stiffer throughout for heavier riders or loaded luggage.
Do these shocks come with chrome covers?
Standard 412s ship without covers, but Show Chrome covers are available as an optional upgrade on select Harley applications.
Will these improve my bike's handling?
The nitrogen-charged, multistage damping provides more consistent control than stock shocks over bumps and cornering, improving both comfort and stability.
