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.
Enhance your Harley-Davidson Softail's ride with the Progressive 465 Series Monotube Shock. Engineered with a high-pressure 46mm monotube design and deflective disc damping, this shock delivers a finely tuned ride quality. Each unit is hand-built, dyno-tested, and features a hard chrome 16mm shaft with a 5-position rebound adjuster for precision tuning.
This Progressive 465 Series shock is designed to bring a new level of performance and comfort to your Harley Softail. The high-pressure monotube design ensures consistent damping by preventing cavitation, while the deflective disc valving provides a progressive damping curve that adapts to various road inputs. With the ability to adjust rebound, you can dial in your suspension to achieve the perfect balance of control and comfort for your riding style.
Whether you're looking for a firmer, more aggressive feel or a smoother, more compliant ride, the Progressive 465 Series Monotube Shock provides the adjustability to achieve it. The robust construction and precision engineering mean this shock is built to perform and last. Upgrade your Softail's rear suspension and experience a significant improvement in handling, stability, and overall ride enjoyment.

Installed the 12.2 standard on my 19 Breakout 114.. got a 2 drop from factory before setting sag.. Ive rode it 80 miles so far.. a little stiff but thats expected.. 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.
