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.
Experience unparalleled control and adjustability on your Harley-Davidson M8 Softail with Progressive 465 Series R.A.P. shocks. These high-pressure gas monotube shocks feature a 46mm bore with deflective disc damping, delivering superior ride quality. The standout Remote Adjustable Preload (R.A.P.) system allows for tool-free adjustments, making it easy to fine-tune your ride on the fly.
The Progressive 465 Series R.A.P. shocks are designed for riders who demand precision and convenience. With remote adjustable preload and a 5-position rotatable rebound damping adjuster, you can quickly adapt your suspension to different loads, riding styles, or road conditions without needing a toolkit. This level of on-the-go adjustability ensures your M8 Softail performs optimally in any situation.
Whether you're riding solo, with a passenger, or loaded with gear, the R.A.P. system allows you to quickly adjust your spring preload to maintain proper sag and handling. The range of available lengths also lets you customize your bike's ride height for a personalized stance. These shocks are a premium upgrade for any M8 Softail owner looking for both performance and unmatched adjustability.
What does R.A.P. mean on these shocks?

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.
