Instantly noticed a profound difference in my ride. Turning was easier and the bike felt so stable. When I adjusted the suspension for my wife and passenger, she noticed a profound difference in comfortability and commented several times throughout the ride. Only criticism is that it is difficult to see the notches when adjusting the suspension.

I am a big guy so I wasn’t sure about these shocks but after a quick conservation with the support team they said these will work. Well I got them and set them to max and it was like sitting on a brick. They had no movement in them at all. I had to soften them up half way. I am very happy with these shocks and glad to have replaced that ok’d air ride system I had on my road king. Firmest was great and install wasn’t bad either. I had a friend help me as all I had was a floor jack but we got it done in about a hour. I hope this review helps you in your decision. I went with the super duty shocks.

I suffered a shock failure. Actually looks like a double failure. I didn’t notice until the ride shock rebound became unbearable. I was told by my local wrench that finding progressive shocks was difficult, but J&P came through just as they have done many times in my 40 years of riding. Watched YouTube and did the install myself in under 1 hour. The old 99 Road king rides like a dream once again. Thanks J&P.

Easy install and looks good on the bike. Haven't tested them out yet because was completing the front forks with Progressive mono-tube kit for 14' SGS. I've had other Progressive rear and front springs upgrade on my previous bike (15' Street Bob) and loved the performance, so i'm I'm sure these will give me the same satisfaction!

Great shocks at a fair price. Had an issue with the 12" progressive 444 so I obtained an RA # through Progressive. J&P then warrantied the shocks with no hassel. They even let me get a 13" shock as it was the same cost. J&P has the best customer service I've found. I will spend all my bike $ with J& P. Now, the shock rides great, better than stock, and the manual adjustment makes it easy to adjust when, if needed.

Got tired of the OEM air shocks. Picked up the 444's - 12" for my 2001 Road King. Got the chrome models. The ride us much better than stock. I ride solo and running at the the softest setting. I called the tech line to make sure I understood the adjustment directions. Quick courteous response to progressive. JP shipped quick too.
