Progressive 412 Series Shocks – Product Review

Progressive 412 Shocks with Chrome Covers

So you bought a Harley Davidson motorcycle and you want to make an improvement to the handling and comfort of your ride. Have the stock rear suspension replaced with Progressive shocks ASAP. After riding my Dyna Lowrider for over 10 months I started to notice the ride was kinda rough. Speed bumps, stutter bumps and potholes were jarring my kidneys and spine. I don’t have an intercom system to warn my passenger about coming bumps and she was taking them pretty hard. Everytime I saw a bump I would cringe for her sake. Then the shocks started to get worse and I started wearing a kidney belt (yes I know, I am a spaz).

I had a pair of Progressive 412 Series Shocks installed along with a new rear tire and a K&N Air Filter during my 10,000 mile service a week before leaving for New River Gorge, West Virginia. The work was performed at Custom Cycle & Machine in New Castle, Delaware. They take care of me famously!

The shocks worked fantastic. Bumps are no longer a concern to me or my passenger. The ride feels more responsive in the corners and I haven’t been wearing the kidney belt!

The only thing I don’t like is the fancy chrome covers that cover the adjustable rate preload setting. They are not numbered so I can’t tell for sure if both sides are set exactly the same. The shocks came with a special adjustment tool since the chrome covers don’t work with the standard spanner wrench. I may have to number the settings or see if the covers come off. I might have them put on Diana’s bike and get a different pair of Progressive Shocks for mine. Diana can leave them on the same setting. I on the other hand need to adjust them depending on the amount of luggage I have on board and if I have a passenger.

Call Custom Cycle & Machine at 302-328-7200 and ask for Scott. Tell him I sent you and they will hook you up with great service.

Or, visit J&P Cycles to order your Progressive Shocks and install them yourself.

  1. Have not seen the benefit to the shock adjustment Make sure you look at several strollers and don’t purchase based off online reviews. Motorcycle

  2. […] puddled cracked up old road to nowhere even though I was on a Harley. Good thing I got those new Progressive 412 series shocks. It was really cool; I felt like I was exploring way off the beaten path. You can check out the […]

  3. do you have lowering shocks for my 2009 fatbob cvo i would like to lower her about 1″,and will that 1″ give me enough wheel clerance at the rear fender thanks for your help ,and what is the cost of the shock s,i think the shocks are a progresive product, full cover shocks?

  4. I had my ’98 FLHTCUI rear air suspension replaced with Progressive’s rear shocks. In a word, they were LOUSY! I complained to the shop and they replaced the outer coils. This made a marginal improvement. AT 210 lbs I bottomed out on I-5 from Rocklin to San Diego. I had them installed and the bike sat for a year. When I had the coils replaced, I had to pay for them because they were over 1 year (of course with ZERO miles). I will NEVER buy progressives again. I’ve unloaded the bike for a newer model and I’ll stay stock this time!

  5. Was the Progressive shock an air shock also or did you replace the air shock with a conventional shock? Good info. Thanks.

    You replaced air suspension with regular shocks and expected an equal or better ride? Really?
