3600 mile review

August 13, 2013

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.

I would recommend this item to a friend.

Why did I wait so long

May 11, 2013

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.

I would recommend this item to a friend.

Much better than stock

April 8, 2013

I just put these on last week after replacing my well worn factory shocks. I weigh 205 and I'm 6' tall. The second notch up is perfect for solo riding (standard spring). I could tell the difference in rear end tracking immediately. The back end feels well planted. Firm yet smooth ride. Next up is a fork spring drop in kit to firm up that front end. I tried heavier fork oil and it's still not quite right.

I would recommend this item to a friend.

Progressives on Sportster

September 18, 2011

Don't put Progressive shocks on your sportster they start at 75lbs/inch and on a sportster that may be fine if you weigh in excess of 200 pounds but I weigh 175 and at their lowest setting they only gave 0.25" without me on the bike and less than about an 1" with me on it when I bought the 12.5" version of 412's vs. factory 11.5". This lead to a very stiff ride, as stiff as my original.

I wouldn't recommend this item to a friend.
