My camper really didn't ride bad to begin with, but our land is miles down a dirt road with washes and ditches etc. On a normal tow, stuff inside would shift around, magnets would fall off the fridge, and one drawer would always come open. I wanted to help out the tiny springs that you often hear about breaking on people and with packing in extra water and weight, I figured these would help.The installation was extremely easy on my camper, I do have an over under kit (axle flip) installed.On the first trip out my teen daughter said it felt different and asked why. I honestly thought it felt the same but maybe not as bouncy. On arrival at our off grid land it was a surprise to find that nothing inside moved around, all the magnets were still on the fridge and the drawer didn't open. Impressive that it made that big of a difference on a dirt road, the stuff normally shifted around on blacktop. They are a little pricey but it was worth it.

Very good. Order for a friend and he was very happy.

Glad I put these on for our travel RV. Makes it more stable for road handling on cures and wind.

Unfortunately by the time I got them installed. It was too late to return them. They are to short for my 2016 coachman bhds292. I put new springs on and they are a good half inch away with both washers installed. I will have to make some later.**** update after talking to the manufacturer this is what I was told by them. "We have been advised by our engineer to let anyone know who has a bigger gap than 6.55" to return the kits. Adding more spacers creates a slenderness ratio that creates leverages that can cause it to buckle and fail." Now I don't know what to do with them. $800 is a lot to sit on the self?

Really easy to install and improved the ride.
