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 consistent, controlled ride across various Harley-Davidson models. Their robust design, featuring double-wall steel construction and nitrogen charging, ensures reliable performance mile after mile. Riders can fine-tune their suspension with ease, adapting to different loads and road conditions.
The Progressive 412 Series shocks are a no-nonsense upgrade for Harley-Davidson owners looking for improved handling and comfort without breaking the bank. These shocks combine durable construction with advanced damping technology to transform your ride. Whether you're cruising solo or loaded down for a long haul, the 412 Series provides the stability and control you need.
Optimizing your V-twin's suspension is crucial for both comfort and performance. The 412 Series shocks make it simple with their intuitive preload adjustment, letting you set sag and stiffness for your weight and riding preferences. This adjustability ensures that whether you're carving canyons or eating up highway miles, your Harley-Davidson remains planted and comfortable. Consider pairing these with a fork upgrade for a truly balanced suspension system.
Can I adjust the preload on these shocks?
Yes, the 5-position cam-style preload adjuster allows you to easily fine-tune the ride height and stiffness to match your weight and riding style.
Are these shocks suitable for two-up riding?
Yes, the Progressive 412 Series shocks are available with heavy-duty spring rates, making them an excellent choice for two-up riding or carrying extra luggage. Always confirm fitment for your specific model.
Do these shocks come in different finishes?
Yes, these shocks are available in both chrome and black finishes, allowing you to choose the look that best complements your Harley-Davidson.

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
