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 deliver consistent damping performance with a double-wall steel body, nitrogen charge, and multi-stage velocity-sensitive valving. The five-position cam-style preload adjuster lets you dial in suspension stiffness for your weight and riding style, making them a versatile upgrade for Harley-Davidson touring and cruiser models.
These Progressive 412 Series shocks are engineered to significantly improve the ride quality of your Harley-Davidson Touring, Softail, or Dyna. The robust double-wall steel construction ensures durability, while the nitrogen-charged, multi-stage velocity-sensitive valving provides smooth, controlled suspension action over varying road conditions. Whether you're commuting or cross-country, these shocks offer a tangible upgrade in comfort and handling.
The Progressive 412 Series shocks are a fundamental upgrade for riders looking to get more out of their Harley. Their adjustability allows you to fine-tune the ride for solo trips, two-up riding, or fully loaded touring. Combine these with a matching front fork upgrade to unlock your V-twin's full potential for comfort and confident handling on any road.
Can I adjust these shocks after installation?
Yes. The 5-position cam-style preload adjuster lets you dial in stiffness anytime without removing the shocks, making adjustments simple for different loads or preferences.
What is the benefit of multi-stage velocity-sensitive damping?
Multi-stage velocity-sensitive damping allows the shock to react differently to various impacts, providing a smoother ride over small bumps and firm support for larger hits, improving overall control and comfort.
Will these shocks fit my specific Harley model?
These shocks fit a range of Harley Touring, Softail, and Dyna models. Please use our Shop by Bike tool or refer to the fitment notes to confirm compatibility with your specific year and model 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.
