SO much better than stock!

These shocks have helped so much! I am 6'3" and around 240lbs and they make solo and 2 up riding so much better both in comfort and handling. And no more chewed through turn signal wires! Amazing purchase for my 05 1200 Custom!

Excellent Shock

My sportster was bottoming out with the stock shocks and upgraded to these. With my wife and I at a combined weight of 400 the bike no longer bottoms and is not too stiff either. Very happy with the shocks - clear instructions - easy install.

Installation: Piece of Cake!

Excellent Price, Shipping was fast, Quality topnotch, and the ride difference was HUGH! Installation was completed and I was out for a test ride in under an hour. After a few handling and braking checks, it was off to the open road where I found the ride stiffer than I desired but still better than the stock shocks. Later when riding two up is when I truly became happy with my new purchase.

3600 mile review

I put these shocks on my 2012 FLHX Street Glide literally 2 days before I left from Louisville KY to ride to Sturgis SD. I already had 14,800 miles of riding on my stock shocks and was definately in tune with their flaws of bottoming out. I put just over 3600 miles on these shocks in ten days over some of the roughest roads in the country and they worked flawlessly! Installation was a snap, adjustment was simple, and even with 185lbs of me and 100lbs of gear they never bottomed out. Ride was just as comfortable loaded as empty.

Why did I wait so long

I replaced my fork springs earlier and waited to change the rear shocks. It was mistake. I should have changed them at the same time. My Sportster feels like an all new bike. Big improvement.
