Frequently Asked Questions
Can I adjust preload on the 412 shocks?
Yes — the 5-position cam-style preload adjuster lets you dial in stiffness for your weight and riding style without changing springs.
What's the difference between standard and heavy-duty springs?
Standard springs suit lighter riders; heavy-duty springs are stiffer for heavier riders or two-up riding to prevent bottoming.
Do these come with chrome covers?
The base 412s ship without covers. Optional show chrome covers are available on select applications — check your fitment.
How does nitrogen charging help?
High-pressure nitrogen prevents oil aeration and foaming inside the shock, keeping damping smooth and consistent over long rides.

A really nice shock for the $
I bought these for my '06 FLHR and could not be happier. I'm 6' 275 lbs so I went with the heavy duty option. Took about 30 min. to change shocks and the ride has improved considerably, took the jolt out of hitting heaves in the road.

Fell apart just outside of progressives 1 year warranty.
While removing the rear wheel for some other service they just quite literally fell apart in two pieces leaving me with a garage floor full of suspension oil and one unusable shock. Spoke with their warranty rep who told me in so many words that its not their problem. Dissapointed to say the least.

Worth it
So far loving these, the ride is much smoother and an awesome look. Going for the 12" was a good choice, raised it but not too much.
