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.
Optimize your Harley-Davidson Softail's suspension with the Progressive 465 Series Monotube Shock. Engineered with a high-pressure 46mm monotube design and deflective disc damping, this shock provides responsive handling and a remarkably smooth ride quality. Each unit is hand-built, dyno-tested, and includes a 5-position rebound adjuster for precision tuning.
The Progressive 465 Series Monotube Shock is a premium upgrade for Harley Softail riders seeking superior performance. The 46mm monotube design ensures consistent, fade-free damping, while the deflective disc valving reacts instantly to changes in road conditions. With the ability to fine-tune rebound damping, you gain greater control over how your Softail responds to bumps and corners, enhancing both safety and rider confidence.
Installing a Progressive 465 Series Monotube Shock means transforming your Softail into a more capable and enjoyable machine. The precise engineering and high-quality components work together to minimize harshness and improve stability, whether you're navigating city streets or pushing your bike on twisty roads. This shock is a direct bolt-on replacement, delivering immediate and noticeable improvements to your ride.

Ill set sag and tweak the rebound and see where she goes.. overall Im very impressed with this shock for what it it.. we caint all afford air ride . Lol
Installed the 13.5 heavy duty in my 2019 slim. It has given me about an inch of extra clearance. Now I have to be really be pushing it to scrape the floor boards.
Outstanding fit and finish. Fits like a glove and the owner was able to place her feet flat on the ground.
