Difference is night and day

By   on  Verified Purchaser

Replaced my Harley air shocks with Progressive 444 shocks, the difference is night and day. My wife no longer slaps me on the helmet when I hit a bump.


These are the shocks Harley needs to use! What a great ride now with the 444!

By   on  Verified Purchaser

You will need a 3/4 wrench, a 3/4 socket and torque wrench, and a jack to take the load off the back tire. It took me longer to get ready and the saddle bags off than it did to change out the shocks. There is only 4 bolts. The ride difference from the air shocks to the 444's is off the chart! I went over the RR tracks by the house and that usually jars my back teeth! I was blown away when my bike went over those tracks like they were not there. Very important, you need to set the sag. There is a great video on how this is done. You can find the sag for your bike on the Progressive Suspension site. You need these on your Harley! Cornering is there, my bike is like glued to the road now.


Wow! What a great ride! 444 rules!

By   on  Verified Purchaser

I researched the different shocks available and I am glad I chose the Progressive Suspension 444 series heavy duty, 13", shock for my 2009 Street Glide. I picked up this bike in May of 2022 and did not like the rear suspension. I installed the shocks, set the SAG, and was blown away at the ride. The RR tracks down the street that would jar my back teeth was like they were not there! The handling has greatly improved! When cornering it no longer feels like the bike is going to slide out from under me. The bad lanes on I40 no longer are a problem either! If you have a Harley with air shocks, you need the 444 Series!


Progressive 444 Series Shocks

By   on  Verified Purchaser

Well I can't give a full honest review, what I can say that I got them in a very timely manner. But, as all the snow was almost gone the temp dropped and a storm hit us hard and the roads again are covered in ice so there is no ride time on them. But they look very nice.


Nice replacement

By   on  Verified Purchaser

Bought these for my 1998 Honda Valkyrie. They are a huge improvement over the OEM shocks that I replaced! Their pricy! I’m hoping that I’ll get my money’s worth!


Nice ride

By   on  Verified Purchaser

Bought the 444HD as a replacement for leaking stock airshocks on my flhtcu tourer. Installation is straight forward, you will need to press in sleeves into the shock isolation donuts. After that it is bolt on. They adjust easily. The shocks are a bit firm when solo, but perfect when 2 up. Honestly I prefer a firmer suspension so these are good with me. A very worthwhile upgrade. I researched other brands, but just could not justify twice the price over what PG was offering these for.


Big difference over factory

By   on 

So much better than factory. Wallowing in the turns has stopped and the bumps feel much better. If our roads were better I wouldn't be as ecstatic. Easy install.


New Shocks - Outstanding!

By   on  Verified Purchaser

I installed these shocks on my 2006 Road King Classic today and took it out for a spin. WOW! I should have done this years ago! I’ve owned this bike since new and have put 114,000+ miles on it. All of those miles were with the stock air shocks, so I didn’t know what I was missing! I changed the fork oil and put these shocks on and it really smoothed up the ride. I have deemed this month my “Suspension Month”. It started with a new front motor mount, then the shocks and front fork oil. On my next available day I’m changing out the rubber isolators on the front swing arm shaft. I call them “hockey pucks” and they are the last part of the puzzle. Again, I’m very impressed with these shocks. I picked the 13” versions which kept the same ride height and since I often ride solo, I got the standard duty versions. Highly recommended.

Questions & Answers

Ask Question

I own a 2014 xl1200c ,do you know the stock length of shocks.I would like to upgrade but I can't find a answer to my question as they are all over the place with sizes on the net. Thank you

That 2014 XL1200C would have come with 11.5" shocks from the factory.

By Andy
Answer Question

Heavy duty or super duty

What is the difference in weight rating for the heavy duty and super duty springs?

Progressive recommends that standard duty shocks be for riders weighing less than 250 lbs. Any rider/passenger combination more than 250 lbs would be going for heavy duty shocks.

By Andy
Answer Question

Heavy duty for solo riding at 190 lbs?

I am having trouble deciding between standard and heavy duty Progressive 444 11.5" for my 2021 Indian Scout. I weigh ~190 lbs and primarily ride solo, but 1/4 the time I have a passenger (~140 lbs). I am primarily interested in these shocks (which I had on a previous bike) for the passenger comfort, so was leaning towards the heavy duty. My concern is how that will impact the solo experience. What is the impact to a solo rider below the 250 lbs mark when using heavy duty shocks? Thank you.

For your situation, it would be best to stick with the standard duty shocks. If your passenger is only with you a 1/4 of the time, you can simply crank up the preload to offer a little more comfort for the added weight.

By Andy
Answer Question

What size shock is Oem on a 2021 street glide special

The stock length shocks on the 2021 FLHXS Street Glide Special would be 12".

By Andy
Answer Question

I have a 2010 Harley forty eight,as I am sure you know every bump is murder. I had read from above that you recommend staying with the OEM length I think it is 11". what is the difference between the 444 and the 412? I really want a smoother ride. Thank you.

Most likely, what's causing the pain is that the shock spring rate is below what you require for a comfortable ride. It's mostly the spring rate, not the shock valving, that's causing the jarring effect when you hit the bumps. Second to that, comes to the quality of the valving of the shocks. In other words, you can have a great set of shocks, but if you're a 250 lbs. rider, and the springs on those shocks rated for a 160 lbs. rider, it's going to be a painful ride. Third to that, of course, comes the length of the shock. You can almost always put a shorter shock on the bike and have it work for your needs, so long as it's sprung correctly. All of that brings us to your particular situation. Progressive recommends heavy-duty shocks if you're over 220 lbs. solo and/or ride two-up at least 50% of the time. So be sure to take that into consideration when choosing the spring rate you need for your bike. And you're indeed correct, the 2010 model year Sportster Forty-Eight uses 11" shocks as stock. So be sure to choose that length in order to retain the stock ride height and overall handling characteristics. As far as the 412 versus the 444 shocks question goes, you will get a smoother ride out of the 444 series shocks. The internal valving is significantly better, and that's what really provides the feel you get when riding the bike. Yes, the 412 shocks will be a lot better than the stock items on your bike, without question, but if you were to compare the 412 against the 444 in a back-to-back ride over the same road, you'd find the bike handles better when the riding gets spirited as the 444 does a better job of keeping the rear end in contact with the pavement. That ability translates into better feel and consequently, more confidence in the bike's handling. Plus, with the 444 shocks, you have the ability to adjust spring preload by hand, whereas the 412 shocks require the use of the included C-spanner to do that. Being able to adjust preload on a whim is nice for situations such as picking up or dropping off a passenger.

Answer Question

Can I order the progressive 444 shocks with a heavy duty spring for 2004 ultra classics Harley

You most certainly can order heavy-duty 444 shocks to fit your machine. Once you select your bike from our fit guide, you'll be presented with the available options to fit the exact model you have: color, spring rate and then shock length. For reference, the 2004 Ultra Classic shipped from the factory with 13" long shocks. So, unless you want to lower the rear end of your bike, choose the 13" option to retain the stock suspension geometry for your bike.

By Staff
Answer Question

I am replacing OEM Air shocks, I do not want to lower my 2007 Street glide. Will these keep the same height?

The OEM shocks that shipped with the 2007 FLHX measured 13" eye-to-eye. So long as you were to choose that length from our fit guide, there'd be no difference in 2007 FLHX ride height.

By Staff
Answer Question

How well will these work on a bagger two up with a combined weight of 390 lb. and gear

The stock air shocks work good till the air bleeds off then you have to refill every 4/5 days ,with out air they bottom easy .

There's an old adage that says "you don't know what good suspension is until you've tried it." That certainly holds true with Progressive's shocks. For your particular needs, (assuming you're riding two-up at least 50% of the time), your best bet would be the heavy-duty spring rate shocks that are of the same length as stock. You'll find the ride quality is significantly improved and the bike will handle a lot better. In addition, since you're putting heavy-duty spring shocks on the rear of the bike, you'll want to match the front fork spring rate for the best possible ride. To do that effectively, check out the Progressive Heavy Duty Fork Spring Kit.

By Staff
Answer Question

I have 12" stock shocks now, should I stay with 12' progressive shocks or longer ?

2014 Harley Low Rider FXDL

It really depends on what you're looking to get out of the bike. If you're want to improve the overall ride, then your best bet would be to stick with the same length shocks as OEM. Conversely, if you want to change the way the bike steers, then a different length shock may be what you're after. Generally, a longer rear shock will quicken steering at the expense of mid-corner stability. A shorter shock will do the opposite. In either case (improving the ride or changing the way the bike handles) the most important thing you should take into consideration is spring rate: standard or heavy-duty. With Progressive's Shocks, 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, it would be wise to employ heavy-duty springs there as well.

By Staff
Answer Question

Is this a gas shock?

These shocks are charged with nitrogen that's separated from the fluid-controlled valving by an internal piston. The piston itself allows fluid volume to expand and contract with heat as you ride. In doing so, you get consistent performance from these shocks no matter how rough the road may get.

By Staff
Answer Question

Is the price for 1 shock or a pair?

2006 Honda VTX 1800F Chrome 12.5 inch

For the 2006 Honda VTX1800F, Progressive's 444 Series Shocks come in pairs. Progressive Shocks are sold in pairs for machines originally equipped with two shocks.
