Your cart is empty.After more than a decade of ruling the roads with the road proven 440 Series shocks, unveiled another breakthrough design. Dubbed Frequency Sensing Technology (FST) for its unique ability to dynamically adjust damping as you ride. The result is superior performance no matter the road conditions. A top mount threaded preload adjuster allows for fine tuning with a simple twist of the cap. Deflective disc valve. Adjust spring pre-load by hand, no special tool needed. Progressive rate spring. Standard spring rate and chrome finish.

I purchased just over a year ago to replace the stock suspension on a 2016 FLHTP. I had the bike about 4 months prior and the weight of my girl and I made the ride uncomfortable. We didn’t bottom out it was just too spongy even with max air pressure in the shocks. After installing these the ride was a dream. No more floaty feeling, no smooth and comfortable ride. It’s now been more than a year and these shocks continue to work as the first day I installed them. I highly recommend these.

Not for my bike. Did not work.

As you know at $450 a set these shocks are expensive. I have a 2013 Roadglide and the air shocks on this bike from the factory were very stiff. I have 4 Harleys currently and have had about 10 Harleys over the years. I have never had bike that road like a hard tail until I purchased this roadglide. I bought the 13" because that is the max that would fit. The original airs were 12". I could not visually notice the raise because when I took the bike off the jack, the new shocks did compress some. The ride is a lot different and the handling did not seem to change. I will be taking this bike for a 5000 mile ride in a couple of weeks which will be the real test. For now I will tell you the ride is much smoother and if they hold up on my trip well, then they are worth the money.

Nice upgrade from stock air shocks. Like one of the first comments on this thread, I ride 2-up a lot and my air shocks always seemed to lose pressure on a regular basis. I'm about 240lbs, and fully loaded with passenger, cold weather and rain gear we're probably close to 400 and I was always having to adjust air pressure, even after only a couple days. Also, my '13 Electraglide classic didn't come equipped with the proprietary air pump that is needed for the smaller schrader valve, and I thought it was lame that it wasn't included with purchase of 20 thousand dollar bike(bad salesmanship - since I wasn't aware of needing one). So I began the journey a little jaded on the stock shocks after having to purchase a 50 dollar air pump just to maintain the pressure on long rides. Riding single with the air shocks was fine, 2 up always bottomed out on the hard bumps. You can't really go past 30-35 psi on stock air, because 35 unloaded equates to nearly 50 psi fully loaded, and you risk blowing out the stock air shocks since 50 psi is maximum pressure according to the documentation.I've taken the Progressive 444 HD spring shocks out on a solo ride so far and I can already tell the difference from stock. The road feels more disconnected from the rider - smoother overall. I felt the hard bumps on a street near my house riding solo with the stock suspension, and the same bumps on these shocks is significantly dampened. I love the fact that the preload can be adjusted by hand, and that I don't need to bring an air pump along for the adventure. I'll update this comment when I ride 2-up with the new shocks.Update:I've ridden 2-up many times since this purchase including a long 1500 mile weekend trip, last Labor Day. These are the shocks you upgrade to from stock, no doubt. All previous points apply to 2-up as well.

Unfortunately I did not get the same results as other reviewers on my 2009 Ultra.Although rebound is adjusted per recommendation, ride over small bumps is annoyingly rougher than original air shocks. Surprisingly these 444 HD shocks will still bottom out.My experience certainly is not the norm based on the other reviewers but I will be re-installing the Harley air shocks.

I have a 2004 HD Electra Glide Ultra-Classic (FLHTCUI) that had the stock 'air-ride' rear shocks which required constant attention when riding two-up with luggage. The stock air-ride from Harley is fine when riding one up but when you really load up I found it to lose air constantly on trips and grew tired of dragging out the hand pump to maintain proper PSI to avoid bottoming out on rough roads or railroad crossings.I emailed a guy over at Progressive and asked a few questions and settled on the 444-4020 13" shocks. These shocks are adjustable by hand cranking the top of the shock. I'd be nice if they'd etch a marking on the collar of the shock to help you keep track of full turns but one can do that easily with a spot of paint. Keep in mind when adjusting these shocks on a bagger, you'll need to remove the bags to change the stiffness of the shocks. The first thing I did after installing these shocks was leave them at full rigidity and left my side bags at home. As anticipated, the ride was too stiff so I'd get a feel of it going over bumps and pits, pull over and give them one full turn and try it again. Then I picked up the lady and we gave it a nice test hitting driveway aprons at a good clip and NO BOTTOMING OUT. Nice. I think it takes a little time to find the sweet spot, but it sure is worth it so far. Honestly I think I'm still riding them a little on the stiff side but the bike handles so much better and will only improve when I locate that perfect spot for riding one-up.Also these are a breeze to install. If you swap out the air-ride shocks, don't forget to keep your old shocks upright so you can sell or store them, otherwise they'll leak and become useless. There are other manufacturers of shocks out there but when it comes to price versus performance, I decided on these and I can't see being any more pleased.Like Frank said over at Progressive; it may be a little extra work moving your bags to adjust these shocks, but isn't a great ride worth a little effort? Yes it is Frank. SOLD.
