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.
Progressive 412 Series shocks are engineered to deliver a smooth and consistent ride for your Harley-Davidson, combining durability with tunable performance. Their robust double-wall steel construction and nitrogen-charged damping ensure reliable operation. With easy preload adjustment, riders can customize their suspension feel.
Transform your Harley-Davidson's handling and comfort with the Progressive 412 Series shocks. These shocks are built to last, featuring a durable double-wall steel construction that stands up to the rigors of the road. The advanced damping system, combined with a convenient preload adjuster, allows you to fine-tune your ride for optimal performance and comfort, no matter the journey.
The 412 Series shocks give Harley-Davidson riders the power to dial in their suspension. Whether you prefer a softer cruise or a firmer, more responsive feel for spirited riding, the 5-position preload adjuster makes it simple to achieve. This level of adjustability ensures your bike performs exactly how you want it to, enhancing both safety and enjoyment on every ride. Consider a fork spring upgrade to complement these rear shocks for a fully balanced suspension.

I bought these for my '06 FLHR and could not be happier. I'm 6' 275 lbs so I went with the heavy duty option. Took about 30 min. to change shocks and the ride has improved considerably, took the jolt out of hitting heaves in the road.
While removing the rear wheel for some other service they just quite literally fell apart in two pieces leaving me with a garage floor full of suspension oil and one unusable shock. Spoke with their warranty rep who told me in so many words that its not their problem. Dissapointed to say the least.
So far loving these, the ride is much smoother and an awesome look. Going for the 12" was a good choice, raised it but not too much.
Just changed from my stock Harley to the 13-in and what a difference it made. Bike handles better and rides better
