Good product.


Thanks for the product

By   on  Verified Purchaser

These shocks give me more stability for when I'm riding.


422 definitely worth it

By   on  Verified Purchaser

Definitely worth the money. Takes a little bit of adjusting. I'm 6'3" 340 pounds so you have to ride it around a little bit and then adjust, ride it a little bit and adjust, but they are definitely working.


Great product, Great Service!

By   on  Verified Purchaser

First of all, these shocks are great. Customer service was great to work with. Very helpful and very professional.


Awesome shocks

By   on  Verified Purchaser

Great shocks and a great price. I installed the standard 422`s on my 03 Fatboy to replace stock shocks. Love em!


05 softail deluxe

By   on  Verified Purchaser

According to Harley-Davidson the stock shocks on the 05 deluxe were designed for a single 180 lb rider. I'm 6'4" and go around 330 lbs. The stock shocks didn't just make for a terrible ride, at my weight they were downright dangerous. Aside from frequently bottoming out, they were so soft I couldn't even keep it going straight down the road and cornering was like rolling the dice. I also ride 2 up 30-40% of the time which was downright suicidal. The shocks were an issue that needed remedied immediately so I ordered a set of the 422 series heavy duty shocks and adjusted them to approx 80% to accommodate the 460 lbs they would need to support when riding 2 up. I had no reference as to the adjustment, it was an educated guess. Immediately after install I was concerned the 80% was too much. The 1st ride had the rear end hopping off the ground with every bump and felt like I was riding a rigid frame. A word of advice, ride 2 up as often as possible until they are broke in. They got better with every ride and 80% turned out to be perfect for solo riding or going 2 up for the stated weights when broke in. I should also note that I did NOT need to adjust the front forks. I was concerned that the front end might dive when cornering but it does not, it corners perfectly. To be clear, these shocks WILL require a brake in period, it's just the nature of the beast. Once broke in you will be so glad you made the change.


Get these!

By   on  Verified Purchaser

Yeah baby! I can finally reach the ground and cornering is so much easier. I didn't even lower the front shocks, no need to but that's just my preference. A bit stiff but it can and will be adjusted.


FLSTF Crusin'

I purchase a set of Heavy-Duty Progressive 422 adjustable shocks for my 2007 Fat Boy. These puppies ride smooth! They allow me and the wife to saddle up with loaded bags without bottoming out. Adjustment is fairly easy with the provided spanner. I should have purchased the RAP version for easier adjustment without tools. Great replacements for blown out factory HD shocks.

Questions & Answers

Ask Question

I am 195 lbs at 5' 7". I ride solo 90% of the time and ride aggressive. What rear shocks would be good for my 2010 Heritage Classic?

It would be suggested to go with the standard rate shocks for your weight/ride style for your 2010 FLSTC.

By Andy
Answer Question

We have a 2008 Heritage Classic. Between my wife and myself the 2 up weight will be 325 lbs. Will the Progressive 422 series shock be the right shock?

Yes, the heavy duty 422 would be what you would want to go with. Once installed you can then adjust the preload and ride height to your liking.

By Andy
Answer Question

I'm 6'5" & 225lbs hardly ever ride 2 up on this bike. What is recommended standard rear shocks or heavy duty on the 422 Progressive?

Custom riding 1 up 99% of the time.

You would want to go with the heavy duty version. Your weight is just over their 220 lb reference for choosing between the two so if you do go with the heavy duty version, you may need to back off the preload if you notice it feeling too harsh when riding. Same goes for the opposite affect of if you are a more aggressive rider and it feels soft you can adjust the preload to make the ride a little more firm.

By Andy
Answer Question

I'm 280 pounds. Will I need to adjust the shock before putting on my 05 deluxe?

If purchasing the Heavy Duty version, it should be pretty close out of the box. You may have to give the bike a ride to see how it's handling and make adjustments afterwards.

By Andy
Answer Question

Me and wife weigh 370 we ride a lot together in the city with bad streets do I go heavy duty or not

1991 HD fatboy

If you're riding two-up at least 50% of the time, yes - go with a set of heavy-duty rated shocks. Progressive recommends heavy-duty shocks for anyone that rides two-up at least 50% of the time, or solo riders that weigh over 220 lbs.

By Staff
Answer Question

new to bikes. my 04 fxsts sits damn near straight up on the kick stand. will raising the rear help with that?

If the bike has been lowered or has failing suspension, that could be the cause. I would suggest inspecting your side stand. If the bike is lowered you would want to purchase a lowered side stand for a proper stance when on the stand if you just wish to make it sit better.

By Staff
Answer Question

Is there anyway to raise the suspension on a 2005 deuce

With conventional type shocks they are all set at stock length or lower. You would have to switch to something like the Legends Aero Air Shocks to gain and adjustability to raise the motorcycle from the stock height.

By Staff
Answer Question

When riding 2up my passenger and my weight add up to about 425 lb, without gear, should I go with heavy duty 422 Progressive shocks for my 2007 heritage softail?

Yes, if you're riding with a passenger at least 50% of the time, we recommend that you order a set of heavy-duty Harley-Davidson Heritage Softail shocks from Progressive Suspension.

By Staff
Answer Question

Can I raise the height more than the stock height?

Progressive's 422 Series Adjustable Shocks are adjustable from stock ride height up to 2" lower than stock. They do not have provisions to extend past stock length to raise the motorcycle on a Softail

By Staff
Answer Question

With the bike lowered the two inches how much does it affect the ride

If you were to just lower the rear on its own, steering would be slowed and the bike would tend to run wide on longer corners. That, and the handlebars would make it feel like the bike wanted to "fall" into the turn, so you'd have to work a little harder to keep it going the direction you want. Depending on your tastes, this may or may not bother you. To keep the bike handling same, you'll want to lower the front the same amount. This can be done by installing a Progressive Fork Lowering Kit up front. In doing so, any changes to the rear are mitigated in lowering the front the same amount, thereby keeping steering geometry the same. Your bike will handle just as it did before. Actually, it'll be noticeably better since all suspension components have been upgraded. One thing to keep in mind is spring rate. Choosing the right spring rate will make a big difference in how your bike responds to a Progressive suspension upgrade. With Progressive's suspension components, heavy-duty springs are best suited for solo riders over 220lbs. If you ride two-up and/or with a full load of luggage at least 50% of the time, heavy-duty shocks are also recommended.

By Staff
Answer Question

Does this shock adjust the same number of turns as the original?

These shocks will use the factory Harley Davidson preload spanner wrench OEM part # 94455-89 or the provided Progressive Suspension tool with these shocks. Before installing the Progressive Suspension adjustable ride height shock, spin the non-flanged nut all the way onto the stud mount, followed by a bushing-cup, bushing, and sleeve. Then install these shocks as you would a stock unit as indicated in the OEM service manual. With the non-flanged nut spun all the way onto the stud, the stock ride height is achieved. Once you have installed the other bushing, bushing-cup, and flanged nut, you can now install the safety E-clip. This E-clip is snapped into the groove near the end of the stud mount where the threads stop. This is to serve as a reference point ONLY - when the flanged-nut reaches it you have lowered your ride height the maximum 2 inches.
