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.
Progressive 412 Series shocks deliver smooth, consistent damping through nitrogen-charged, multi-stage velocity-sensitive valving in a durable double-wall steel body. A five-position cam-style preload adjuster lets you dial in support for any rider weight, making these a practical upgrade for Harley suspension without breaking the bank.
Upgrade your Harley-Davidson Touring, Softail, or Dyna with the reliable and comfortable ride provided by Progressive 412 Series shocks. These shocks feature a robust double-wall steel damper body, ensuring long-lasting performance and durability. The high-pressure nitrogen gas charging combined with multi-stage velocity-sensitive damping provides a consistently smooth and controlled ride, effortlessly soaking up road imperfections and enhancing overall stability.
The Progressive 412 Series shocks offer a significant improvement in ride quality and handling over stock suspension. Their easy-to-use cam-style preload adjuster allows you to quickly adapt your bike's suspension to your specific needs, whether you're riding solo, with a passenger, or carrying luggage. For a truly transformative experience, consider pairing these shocks with a high-quality front suspension upgrade.
Can I adjust the preload on these shocks?
Yes – the 5-position cam-style preload adjuster lets you fine-tune support whether you're a light rider or carrying a passenger and gear. No special tools are required.
What does "multi-stage velocity-sensitive valving" mean for my ride?
This technology allows the shocks to respond differently to various road impacts, providing a plush ride over small bumps while firming up for larger compressions, leading to better control and comfort.
Will these shocks fit my specific Harley-Davidson model?
These shocks are designed to fit a wide range of Harley Touring, Softail, and Dyna models. Always confirm compatibility for your specific year and model using our Shop by Bike tool before making a purchase.

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
