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 are engineered to provide a smooth, consistent ride for your Harley-Davidson. Combining a durable design with practical adjustability, these shocks are built to last and perform.
Designed for riders who value both performance and aesthetics, the Progressive 412 Series shocks deliver a significant upgrade in ride quality. Featuring double-wall steel construction, these shocks are robust and built to withstand the demands of the open road. The multi-stage, velocity-sensitive damping, coupled with a high-pressure nitrogen charge, ensures consistent performance and excellent bump absorption across all road conditions.
The easily accessible five-position cam-style preload adjuster allows you to quickly dial in the perfect spring rate for your weight, a passenger, or any additional cargo. This ensures optimal comfort and handling, preventing bottoming out and maintaining stability. Available with a brilliant chrome finish, these 412 Series shocks not only enhance your ride's performance but also add a touch of classic V-Twin style to your Harley-Davidson.
Can I adjust these shocks to my weight and riding style?
Yes, the five-position cam-style preload adjuster allows you to easily dial in the compression to match your weight, a passenger, or specific road conditions without needing special tools.
What is the benefit of nitrogen-charged damping?
The high-pressure nitrogen charge prevents oil cavitation and foaming, ensuring consistent damping performance and a predictable feel even during extended rides or spirited riding.
Are these shocks compatible with my Harley-Davidson?
These shocks are designed for Harley-Davidson models. Please use our Shop by Bike tool to confirm exact fitment for your specific year and model before ordering.

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
