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 durable, adjustable suspension for Harley-Davidson motorcycles at a straightforward price point. Built with double-wall steel construction, nitrogen charging, and multi-stage velocity-sensitive damping, these shocks provide consistent performance across a wide range of rider weights and road conditions. Experience improved handling and comfort on your Touring or Softail.
Enhance the ride of your Harley-Davidson Touring or Softail with Progressive 412 Series shocks. These units are engineered to provide a significant upgrade over stock, offering both durability and adjustability. The robust double-wall steel damper body and high-pressure nitrogen gas charging ensure consistent, fade-free damping, even on long rides or rough roads. With multi-stage velocity-sensitive damping, the shocks intelligently adapt to varying impacts, providing a smooth feel over small bumps and firm control through larger compressions.
The Progressive 412 Series shocks offer Harley-Davidson Touring and Softail owners the flexibility to fine-tune their suspension. The easily accessible 5-position cam-style preload adjuster allows you to quickly dial in the firmness to match your specific riding needs, whether you're cruising solo, carrying a passenger, or loaded down with gear for a cross-country trip. This adjustability ensures optimal handling and comfort, transforming your V-twin's ride quality.
Can I adjust these shocks for my riding weight?
Yes, the 5-position cam-style preload adjuster lets you dial in ride height and stiffness to perfectly match your weight, a passenger, or any luggage you're carrying.
Will these shocks fit my specific Harley-Davidson Touring or Softail model?
Progressive 412 Series shocks are designed for a wide range of Harley-Davidson Touring and Softail models. We recommend using our Shop by Bike tool to verify exact fitment for your specific year and model before ordering.
What is the benefit of multi-stage velocity-sensitive damping?
This advanced damping system allows the shock to react differently based on the speed of impact, providing a softer, more compliant ride over small bumps and firm, controlled damping for larger hits, improving overall comfort and handling.

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.
