Rides like a dream.

Easy to install with the right tools. Instructions are a little lacking but the Progressive web site has great videos that helped.

The best way to lower a bike after installing a 21" front wheel. It actually rides better than stock.

I'll admit I was on the fence about if these monotubes would really make much of a difference. I am BLOWN AWAY at how much of a difference they made. It's hard to explain, but it really is like if you have ever driven a high end sports car, everything just feels tight and responsive, firm, but not hard. These were worth every penny, hell... i'd of paid twice as much knowing what I'm getting now. It's unbelievable how sloppy the stock HD suspension is.. and you probably won't even know it until you put this upgrade in. I have my rear end lowered 2", so I lowered the front 1" and my bike feels great. 2013 Street Glide.

Lowered the front one inch on my 2008 Street Glide. Wish I had done it sooner.

Best value for the money

Great product! Instructions were exact, and tech support was second to none... Very pleased!

5 by

Good price, easy installation, great quality, I give it a 10

I just got the new shock cartridges installed and they are wonderful! Less nose dive on heavy braking, and very little front end lift on acceleration. This translates to a more controlled ride and is exactly what I was hoping for.
