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.
Transform your Harley-Davidson Softail's ride with the Progressive 465 Series Monotube Shock. This high-performance shock features a large 46mm bore with deflective disc damping, providing a responsive and controlled feel. Each unit is hand-built, dyno-tested, and precision-tuned to ensure consistent damping and superior ride quality.
The Progressive 465 Series Monotube Shock is a serious upgrade for any Harley Softail owner looking to enhance their bike's performance. Its advanced design, featuring a high-pressure gas monotube and deflective disc damping, delivers a significant improvement in both comfort and handling. With a 5-position rebound adjuster, you can fine-tune your suspension to match your riding style and road conditions, ensuring your Softail stays planted and responsive.
Whether you're carving canyons or cruising the open highway, the Progressive 465 Series shock will elevate your Softail experience. The choice of standard or heavy-duty spring rates ensures optimal support for your specific setup, while the range of available lengths allows for precise ride height adjustments. This shock is engineered to provide a responsive, controlled ride, making your Softail feel more connected to the road.

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.
