About Progressive

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 and a durable, simple design to improve ride quality across all Harley-Davidson models. Their double-wall steel construction, combined with nitrogen charging and multi-stage velocity-sensitive valving, provides smooth suspension control. A five-position cam preload adjuster allows you to fine-tune the ride for your specific weight and riding style.

Why riders pick this

  • Durable double-wall steel construction
  • Nitrogen-charged for consistent damping performance
  • Multi-stage velocity-sensitive valving
  • Five-position cam-style preload adjustment

These Progressive 412 Series shocks are engineered to upgrade your Harley-Davidson's suspension with a focus on durability and rider-tunable performance. Moving beyond basic factory suspension, the 412 Series offers a more controlled and comfortable experience, absorbing road imperfections with greater efficiency and helping your V-twin maintain better traction.

Engineered for Ride Quality

  • Durable double-wall steel damper body construction
  • High-pressure nitrogen gas charged for consistent damping

Optimizing Your Harley's Suspension

The ability to quickly adjust preload means you can easily adapt your Harley-Davidson for solo cruising, two-up touring, or hauling gear. This user-friendly feature ensures that your V-twin performs optimally under various loads and riding scenarios, providing a more personalized and enjoyable experience every time you twist the throttle.

Nice improvement over factory shocks.

Larger piston, better springs and improved dampening all make for a more stable ride, especially in corners, not to mention how much better the 412's look on the bike. Add Progressive springs, Bel-Ray oil and Speed Merchant Pre-Load adjusters to the front shocks and you have one nice handling Sportster.

A must addition to any Sportster

Was unsure if the Heavy Duty version #412-4011C was going to be right for my XL1200C Sportster. Having being 6’0” and just under the 250+ lb rating for the heavy duty service @ 220 lbs solo riding I found that at the lowest pre-load setting they functioned beautifully. Was actually able to experience the ride the other day unexpectantly traveling over a street that was extremely in need of repair. Very pleased with my purchase and glad that I bought the Heavy Duty version of the Progressive Suspension 412 Series Shocks

Great shocks, easy install. Lousy packing. Shock box was great but they put it in a larger box and broke open from Louisville KY to Ft Myers FL. Lucky nothing was missing. Need more stock at Daytona location.

13" standard 412 shocks on FXR. i think the heavy duty would of been a little better choice for my bike.

Bike feels great!

These shocks are probably the best upgrade I've done for my bike yet. They're comfortable and have the right amount of stiffness for a sportier ride. As always revzills customer service is the best!

412 Shocks

This is the 3rd set I've bought in 21 years. The ones i just replaced lasted 11 years of hard riding on crappy road conditions!
