Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
The Progressive 412 Series shocks offer tunable suspension performance with a focus on durability and straightforward design. Featuring a double-wall steel damper body and nitrogen charging, these shocks provide smooth and consistent damping. Riders can easily adjust preload to match their specific needs.

The combination of robust materials and intelligent damping technology ensures your V-twin remains stable and comfortable, whether you're navigating city streets or cruising highways.
The 412 Series shocks are designed to give you more control over your Harley-Davidson's ride dynamics.

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
