Fitment
Fits Harley-Davidson cruiser models. Check fitment details with your bike's year and model before ordering.
Frequently Asked Questions
Can I adjust the ride height with these shocks?
Yes — the 5-position cam-style preload adjuster lets you dial in spring tension to match your weight and riding preference.
Do these require installation by a professional?
Shock installation involves removing the old shocks and bolting on the new ones. Most riders use a shop, but experienced DIY mechanics can handle it with basic tools.
What's the difference between standard and heavy-duty springs?
Standard springs suit lighter riders; heavy-duty springs provide more support and resistance for heavier riders or two-up riding.
Will these fit my specific Harley model?
These fit Harley-Davidson cruisers. Verify your model year and chassis type matches part number 412-4066B before purchasing.
Are these a bolt-on replacement?
Yes — they bolt directly onto your bike's existing shock mounts in place of the factory shocks.
