fantastic shocks. love the ride and the look. Super easy to install with a lift.

Got rid of my stock air ride to get these shocks. A big improvement over stock. Can adjust for single or double up touring in just a few seconds. Should have bought these sooner!

These are even better than I expected!

Good looking shocks with decent rebound. Was happy with the purchase and the price. Remember to order the black, top bolt covers as they don't come with them.

Much better than the stock ones.

They look great, provide a smooth ride and adjust easily - a winner for me.

Great shocks. I'm 200lbs and the ride is perfect. When my wife rides I don't have to adjust the preload and the bike handles perfect. I also replaced the front springs with the Progressive ones. I recommend doing them both.

The shocks where purchased to lower a 2000 Harley Road King for my wife. The shocks accomplished this task and provided a better ride and handling over the stock air shocks.

Great product! Fit my 1995 Sportster 1200 like a charm. With help from a friend, I was able to change these shocks with a car jack!
