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 bring a significant upgrade in ride quality and adjustability to your Harley-Davidson. Engineered for consistent damping, these shocks help keep your rear wheel planted and your ride smooth across varied road conditions. They are a solid choice for riders looking to enhance both comfort and handling.
Unlock a more controlled and comfortable ride for your Harley-Davidson with Progressive 412 Series shocks. These units are built with a robust double-wall steel body and feature nitrogen-charged, multi-stage velocity-sensitive valving to deliver smooth, consistent damping. Whether you're cruising solo or loaded down for a trip, the 412 Series helps absorb impacts effectively, reducing harshness and improving stability.
The 412 Series shocks are designed to provide a noticeable improvement over factory suspension. With their progressive spring rates, they offer a supple initial feel that firms up as the suspension compresses, preventing bottoming out. The easy-to-use cam preload adjuster means you can quickly fine-tune your ride height and stiffness, ensuring optimal performance for your specific setup and riding preferences.
Can I adjust the ride height with these shocks?
Yes, the 5-position cam preload adjuster allows you to tune the ride height and stiffness to match your weight and riding style.
Will these shocks change the feel of my ride?
Absolutely. Progressive 412 Series shocks are designed to provide more consistent damping and better control than many stock units, smoothing out bumps and improving overall stability.
Are these shocks difficult to install?
Installation typically involves basic hand tools and can be done by a competent home mechanic. If you're unsure, we recommend professional installation.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
