Frequently Asked Questions
Can I adjust the ride height after installation?
Yes. The 5-position cam-style preload adjuster lets you dial in ride height without tools — adjust for solo or two-up riding and rider weight.
What's the difference between standard and heavy-duty springs?
Standard springs suit lighter riders; heavy-duty progressives handle heavier loads without sagging, maintaining consistent damping across weight ranges.
Do these require any special installation tools?
Progressive 412s bolt into existing shock mounts — no frame modifications needed. Standard motorcycle tools and a shock compressor are recommended for safe installation.
Are the show chrome covers included?
Show chrome covers are optional on select applications — check fitment details when ordering to see if your model qualifies.
How long will these shocks last?
With proper maintenance, the double-wall steel body and nitrogen charge deliver consistent performance for the life of ownership.
