Frequently Asked Questions
Can I adjust the preload myself?
Yes — the 5-position cam-style adjuster lets you dial preload without special tools. Rotate to match your weight and riding style.
What's the difference between standard and heavy-duty springs?
Heavy-duty springs suit heavier riders or two-up cruising. Standard springs work best for lighter riders or solo riding.
Do these shocks improve my bike's handling?
Yes. Nitrogen charging and multistage damping give you more controlled compression and rebound than many stock shocks, improving ride quality and cornering.
Are Show Chrome covers included?
No — chrome covers are optional on select applications and must be ordered separately.
