Fitment

Fits Harley-Davidson models. Verify your specific year and model before ordering, as spring rates and geometry vary by platform.

Frequently Asked Questions

Can I adjust the preload myself?

Yes. The 5-position cam-style adjuster lets you dial preload up or down without tools — ideal for tuning to rider weight or load.

What's the difference between Standard and Heavy-Duty springs?

Heavy-Duty springs suit heavier riders or those carrying passenger and luggage. Standard springs work for lighter riders and solo use.

Are these shocks valved for street riding or track use?

These are street-tuned shocks with multi-stage velocity sensitive damping for smooth, controlled ride quality on public roads.

Do these come with chrome covers?

Standard models ship without show chrome covers. Optional full chrome covers are available on select applications — check fitment before ordering.

Will these improve my bike's handling?

Yes. The nitrogen gas charge and multi-stage valving reduce bottoming and harshness compared to worn OEM shocks, improving stability and comfort.

Big Man's Shock Absorbers

I installed these on my 2013 Harley Road Glide Ultra about two weeks ago. Being 6'4" tall and weighing 350 lbs I did quite a bit of studying and asking others before making my purchase. With about 300 miles on them I can honestly say WOW! what an upgrade. I opted for the heavy duty 13.5" version due to my heftiness. These have 4 settings for stiffness/sag I've settled on the second softest after trying them in settings 2 and 3 I found three to be a bit too rigid even with my weight. The only reason I didn't give them 5 stars is because Its impossible to rate the durability at this point. They ride great so far and if they hold up I'll rerate them to 5 stars. The only con is that having a fine pair of shocks on the back end makes the front end seem wimpy. Now I'm seriously considering the progressive heavy duty fork springs for the front. I hope this helps you make your decision.

Buit for riding

These shocks are the real deal for the money. If you are running the stock seat on a touring bike, follow the weight instructions provided by Progressive Suspension. But if you are close to 250lbs or you have changed out your seat for one that puts you further back a little, go with the Heavy Duty ones because generally speaking more weight is placed towards the rear of the bike when you switch out seats. This is what I did and couldn't be happier. Riding over rail road tracks or other obstacles is not a consideration anymore. I don't bottom out, even at high speed and the increase in overall handling is well worth the cost. Much better than stock suspension. Also, I went taller by half an inch and I'm happy that I did. I put them on an 09 Road King Classic.

Best purchase

I'm a big guy 6'2 320lbs my wife is tiny 130lbs so I needed an upgrade the stock airshocks didn't cut it so I purchased the progressive 412s and wow it's a whole new bike I got the shock in a one inch longer length for added travel and by the way I ride a 2013 roadglide custom I recommend it to anybody that is large like me to get the shocks with the hd springs there is no more bottoming out and the ride is awsome

So smooth!

I weigh over 300 lbs (I know I'm fat) so I purchased the heavy duty, also bought the 13" for a little more cushion. Solo I ride it with one click on the preload, haven't had the chance to ride 2 up but the preload is real simple with the tool provided (kept in the saddlebag). The shocks are very responsive and make my ride so smooth! <br /><br />Install is super easy and can be done by yourself though I had a brother help to make sure the bike didn't tilt off the jack.<br /><br />$299 for these is a good price for it. Durability I'm assuming a 5 though I've only put about 750 miles on them so far. Washers provided allowed for it to fit perfectly and finish looks nice though my saddlebags cover them.<br /><br />My bike is a 2010 FLHX Street Glide.

Excellent option for the stock air shocks

They bolted right up. The settings range from single to 2 up long distance touring comfort. My wife Nd I always ride tigether 2 up. We found the 3rd notxh to be the most pleasant to cushion bumps but prevent bottoming out. Would def recommend !
