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 offer Harley-Davidson riders a significant suspension upgrade at a budget-friendly price point. These shocks provide smooth, consistent damping and the ability to fine-tune your ride for comfort and control.
Uncork the ride quality of your Harley-Davidson with Progressive 412 Series shocks. Engineered with a double-wall steel damper body and nitrogen-charged, multi-stage velocity-sensitive valving, these shocks deliver reliable performance across various riding conditions. Whether you're cruising solo or loaded down, the 412 Series provides a noticeable improvement over stock.
The Progressive 412 Series shocks are designed to give you more control and comfort without breaking the bank. The easy-to-use preload adjuster means you can quickly set up your bike for different weights or riding preferences. This makes them an excellent choice for riders looking for a versatile and dependable suspension upgrade.
Will these shocks improve my ride comfort?
Yes, the Progressive 412 Series shocks are designed to offer more consistent damping and adjustability than many stock setups, leading to improved ride comfort and control on your Harley-Davidson.
Do I need special tools to adjust the preload?
No, the 5-position cam-style preload adjuster allows for tool-free adjustments, making it easy to dial in the ride for your weight and riding style.
How do I choose the correct spring rate?
The 412 Series is available with standard or heavy-duty progressive-rate springs. To ensure the best performance, confirm fitment with Shop by Bike and consider your typical riding load and style before ordering.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
