I installed Progressive 412 shocks on my 2010 HD Ultra Classic to eliminate the worthless HD air shocks. The 412's are great, wish I had done it sooner.

Compared to the stock ones is night and day. I ordered the 13 " , my bike is not that close to the ground any more , and i can lean much more . One thing i can say do not think twice to order this shocks ,especially if you live in NYC. Easy to install , although mine looked like they were installed once before i still kept them !

A bit stiff but very much better than the shorties that were on it.

ROBERT on 7/15/2019

Fit good look good ride great

MARTIN on 5/6/2019

I like the ramp style preload adjuster. The dampening is not as progressive as I would have liked, but the overall value is there. It is a step up from OEM on my 2010 Streetglide. I'd recommend.

I love my new shocks, the bike rides and handles better than the factory air shocks. Thank you J&P tech Dude for the great advice.

Sgt Patriot on 7/9/2015

Great fit and look, did not realize just how bad the old shocks were until I took my first spin. WOW what a differance

Important Product Notes

Note: When shocks are different than stock length, clearance must be carefully checked for potentially dangerous interference.
