Did not ship with the bushings and washers necessary for correct installation. The eyelets are not machined smooth and do not have a "trued" surface for mating with a washer, frame or bolt head. Bushings are mandatory so they can be properly torqued during install. After seeing the overall build quality in person, I made the decision to go with a different brand shock.

I purchased these for my 2017 HD Dyna Low Rider. I wanted to get just a tad more of my foot on the ground when backing the bike up. These accomplished that goal with minimal change in ride quality.I would recommend to anyone, and wouldn't hesitate to purchase again if I needed new shocks!

Big difference in handling, height if lowered like myself. A bit stiffer ride , obviously less travel if lowering. Well made.

I returned these. My weight is 220 lbs. and at the firmest preload setting I was bottoming out all the time. Hated the ride. I would not recommend.

Can't comment on longevity as I just threw them on this week but love the lowered look over the stock streetbob height and rode two up with no issues.

these shocks were exactly what i needed for my 2014 harley street bob. they were easy to install one person can do it in about 30 mins. i would just reming anyone going for that really low look, you will lose a lot of travel. which means a stiff ride, I'm good with it but be warned.

It's the most affordable way to lower your bike. The comfort is not bad but it's not great either. B+
