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 smooth, consistent suspension performance with a proven design trusted by Harley riders. Double-wall steel construction, nitrogen-charged valving, and a five-position preload adjuster give you tuning range from light cruising to loaded touring. Experience enhanced control and comfort on your V-twin.

Why riders pick this

  • Smooth, consistent damping from a proven design
  • Durable double-wall steel damper body
  • Multi-stage velocity-sensitive damping for responsive control
  • High-pressure nitrogen charging prevents fade
  • 5-position cam-style preload adjuster for easy tuning
  • Available with standard or heavy-duty spring rates

Elevate your Harley-Davidson's ride quality with the Progressive 412 Series shocks. These shocks are a popular choice for riders looking to improve upon their stock suspension, offering a significant upgrade in both performance and durability. Built with a robust double-wall steel damper body and featuring high-pressure nitrogen charging, they provide consistent, fade-free damping across all riding conditions. The multi-stage velocity-sensitive damping ensures a responsive feel, absorbing bumps efficiently.

Enhanced Ride for Every Journey

The Progressive 412 Series shocks are designed to give Harley-Davidson owners the ability to fine-tune their ride for any situation. The accessible 5-position preload adjuster allows for quick changes to accommodate solo riding, two-up journeys, or when carrying luggage. This adjustability ensures optimal handling and comfort, making long-distance touring and daily commutes equally enjoyable. Consider these shocks as a foundational upgrade for a truly custom V-twin suspension setup.

Common questions

What's the difference between standard and heavy-duty springs?

Standard springs suit lighter riders and normal loads. Heavy-duty springs handle heavier riders, two-up riding, or significant luggage without excessive sag, providing better control under load.

Will these shocks improve my bike's cornering ability?

Yes, by providing more consistent damping and appropriate spring rates, the 412 Series shocks can significantly enhance stability and control during cornering, making your Harley-Davidson feel more planted.

Do these shocks come pre-set, or do I need to adjust them?

The shocks come with a factory setting, but the 5-position preload adjuster allows you to easily fine-tune them to your personal weight, riding style, and load for optimal performance.

Upgrade over OEM

My 2001 RK Classic was in bad need of new rear shocks. Old ones didn't hold air for more than a couple hours and I ride with momma on the back or loaded up for a long solo ride 90% of the time. Rarely do I ride solo without a load or the boss behind me. So after lots of searching I decided the 412s were what I needed since I will be buying a new bike next year. No need to spend a ton of money. <br /><br />Package arrived quickly and after opening and giving the instructions a quick read I was after it. Got the bike on the jack bags off and lower shock bolts on each side out. Top bolts come out next and since I had everything off and out of the way I took time to check out everything and clean things up. Time for new shocks now. Pop in the spacers and put a little bit of blue LocTite on the threads (instructions didn't say it was needed but I feel better with some on there) place top bolts in first and thread them in a little bit. Place the bottom ones in next. You might have to adjust your jack to get the holes to line up but not a big deal. Everything lined up and tightened down (didn't have a torque wrench so I just went until I thought it was good) cleaned up and got the wrench they send with the shocks and I turned them up a click. Put bags on with some weight in them and went for a ride.<br /><br />Noticed right away it was lowered down. Liked the look of it so I'm happy with that. Then after I got out and on the roads that used to jar the bike hard and went down them I noticed that it was a lot smoother. I was so happy with it and enjoy riding even more now<br /><br />I know that the higher price shocks will ride much better than these but I'm incredibly happy with the improvement over the 16 year old air shocks that were on it. <br /><br />So my advice is to have realistic expectations with them. If you are looking for an improvement over old worn out shocks these will do that but won't give you a Cadillac ride. They are under $300 so you have to expect improvement but not an mind blowing experience

A really nice shock for the $

I bought these for my '06 FLHR and could not be happier. I'm 6' 275 lbs so I went with the heavy duty option. Took about 30 min. to change shocks and the ride has improved considerably, took the jolt out of hitting heaves in the road.

Fell apart just outside of progressives 1 year warranty.

While removing the rear wheel for some other service they just quite literally fell apart in two pieces leaving me with a garage floor full of suspension oil and one unusable shock. Spoke with their warranty rep who told me in so many words that it’s not their problem. Dissapointed to say the least.

Shocking

I have bought both high $ and low $ shocks and these work great for the $. Replace your stock air shocks in 10 minutes and off you go... I would buy them again.

Best bang for the buck!

These shocks provided the most radical change to the ride and handeling of my motorcycle. Suspension should be on your upgrade list and these shocks should be your choice.
