One of the best additions I've made. Vast improvement over stock. It absorbers speed bumps and city/highway terrain like a champ without making you feel like you are floating or lost contact with the road.


I think these shocks are amazing to start off. J&P also has the most amazing customer so far. I had the weld inside the top bracket snap. I felt the shock boot hit me in the shoulder and the bike pulled to the left. J&P is already working on sending me a replacement because Progressive has an awesome warranty. I think these shocks were the best thing I’ve put on my bike so far. The two stars is because I’m disappointed in the quality control. Even if this was a freak accident, if it had happened at interstate speeds, I wouldn’t be here.


Great product, put them on my FLHTK and the difference was night and day. Used to feel every bump in the road, now the ride is a complete 180. Highly recommended


These made a huge difference on my 14 ultra. Truly enjoying my ride again. My fellow baggers I highly recommend.


Fast shipping, excellent quality shocks, pretty easy to install, and a great riding improvement on my FLHTCUI. Much better than the stock air shocks, with enough adjustment for any riding conditions.


Very fast shipping, easy to install, and work exactly as described. Very noticeable and positive difference on my FLHTCUI. I have already recommended these shocks to friends.


Worth every penny big improvemt over stock air without the hassle


What a difference! Replace your factory air shocks with a set of Progressive 412 HD's and get your ride back on track.


Easy install so far its a good ride


Looks and works great.
