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 for your Harley-Davidson, built with a durable double-wall steel body and nitrogen-charged valving. The five-position cam-style preload adjuster lets you dial in the perfect ride for your weight and riding style. These shocks provide smooth compliance across the suspension stroke.
Upgrade your Harley-Davidson's rear suspension with the Progressive 412 Series shocks, designed for both comfort and control. The robust double-wall steel damper construction ensures longevity, while the high-pressure nitrogen gas charging maintains consistent damping performance, preventing fade even during extended rides. With multi-stage velocity-sensitive damping, these shocks intelligently adapt to different road conditions, providing a smooth, controlled feel whether you're cruising city streets or tackling winding backroads.
The Progressive 412 Series shocks are a go-to choice for riders seeking to refine their Harley-Davidson's ride quality. The easy-to-use 5-position preload adjuster allows you to effortlessly compensate for varying loads, from solo rides to fully loaded touring. This adjustability, combined with the progressive-rate springs, ensures a plush initial feel that firms up to prevent bottoming out, delivering a balanced and confident ride.
Can I adjust the preload on these shocks?
Yes, the 5-position cam-style preload adjuster allows for quick and easy adjustments to fine-tune the ride for your specific weight and riding conditions.
What's the benefit of progressive rate springs?
Progressive rate springs offer a softer initial compression for small bumps, providing comfort, and then gradually become stiffer as they compress further to prevent bottoming out under heavier loads or larger impacts.
Will these shocks fit my specific Harley-Davidson model?
Shock applications vary by model and year. We strongly recommend using our 'Shop by Bike' feature or contacting us directly to confirm compatibility for your specific Harley-Davidson 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.
