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.
Unleash the full potential of your Milwaukee-Eight Softail with Progressive 465 Series R.A.P. shocks. These high-pressure gas monotube units are engineered for performance, offering precise handling and a tunable ride.
Experience a significant upgrade in ride quality and control for your M8 Softail. The Progressive 465 Series R.A.P. shocks are designed to replace your factory units with a performance-oriented suspension system that's both adjustable and durable. Dial in your preferred ride height and damping characteristics to match your riding style and road conditions.
Each 465 Series R.A.P. shock is hand-built, tuned, and dyno-tested to ensure optimal performance right out of the box. Whether you're chasing a more aggressive stance or simply want a more controlled and comfortable ride, these shocks provide the adjustability needed. Pair them with a front-end suspension upgrade for a truly balanced setup.
Will these shocks change my bike's ride height?
Yes, these shocks are available in four different lengths, allowing you to fine-tune your Softail's ride height from stock to a more aggressive, raised setup.
Do I need special tools to adjust the preload?
No, the Remote Adjustable Preload (R.A.P.) system features a hand-adjustable knob for quick, tool-free preload tuning.
Are these shocks a direct bolt-on replacement?
The Progressive 465 Series R.A.P. shocks are designed as a direct replacement for Harley Milwaukee-Eight Softail models. Confirm fitment with Shop by Bike before ordering.

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.
