These shocks will not lower your bike correct? I hear the 944 shocks will lower it by 1 inch which I do not want
A shopper on May 19, 2018
BEST ANSWER: These are 13", not a lower shock
Hi I want to put these on a ultra classic I weigh 160 and my wife is about 160 should I go with the heavy duty shocks or standard?
james h on Jan 31, 2019
BEST ANSWER: Standard. I have an ultra classic. I weigh 245 lbs. I’m he heavy duty are too stiff for me. I sit on the bike and the shocks don’t even move an inch. I use zero preload. I would like to see what standard shocks ride like just to see if they are a little softer. Definitely get the standard.

Bone jarring bumps in the road are okay now.
I got these for an 05 HD Ultra Classic. I'm 255 lbs. I did not have to set any preload on the shocks. I just barely got 1 inch of sag. If you're lighter than 250, I wouldn't get the heavy duty. They are very comfortable on everything I've gone over. I would like to try out a standard duty pair of these shocks, just to feel the difference. But on aggressive riding on a bad road, I had very good control. I think when I ride two up with my wife, it will be even better.
