Progressive 412 Series shocks deliver consistent suspension performance through gas-charged, multi-stage velocity-sensitive damping in a durable double-wall steel body. The five-position preload adjuster lets you tune the ride for your weight and riding style, while available chrome covers and spring options (standard or heavy-duty progressive rate) customize the look.
Fits Harley-Davidson models. Verify your specific year and frame with Progressive's fitment chart before ordering, as shock applications vary by model generation.
Yes — the 5-position cam-style adjuster is accessible and lets you change preload without removing the shocks from the bike.
Heavy-duty progressive springs support more weight and provide stiffer ride. Standard springs suit lighter riders. Choose based on your combined weight with gear.
Chrome covers are optional on select applications and may be ordered separately. Check if they're available for your specific Harley model.
The 412's gas-charged damping and progressive springing provide smoother, more controlled ride than factory shocks on most Harley models.
Shock installation requires removing the rear wheel and breaking the frame welds on older models — professional installation is strongly recommended.

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.
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.
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.
Just changed from my stock Harley to the 13-in and what a difference it made. Bike handles better and rides better
