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!

5 by

Excellent ride and comfort

Great for the black out look. Not alot of difference from factory, but great quality.

5 by

Easy install. Nice look. Good ride.

5 by

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.

5 by

Much better than the stock ones.

5 by

Look great. Ride nice.

5 by

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.

4 by

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.

4 by

I needed heavier springs.

Easy to install. Improved the ride.

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!
