Frequently Asked Questions

Can I adjust the ride height or stiffness after installation?

Yes — the 5-position cam preload adjuster lets you dial in stiffness to match your weight and riding style without tools.

Do these come with chrome covers?

Standard 412s ship without covers. Optional show chrome covers are available on select applications — check fitment for your model.

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

Standard springs suit lighter riders; heavy-duty springs provide more support for heavier riders or two-up riding with luggage.

Are these a direct bolt-on replacement?

Yes — 412 shocks are direct replacements for factory shocks on compatible Harley models. Check your year and model for proper fitment.

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

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.

Much better

Bolted the shocks on in less than 20 minutes and took off on a 150 mile ride. Night and day difference from the stock air shocks.

Progressive 412 shocks are a lot better ride than the original shocks on my 2003 ultra classic.
