Excellent product and I could tell the difference in less than 5 miles of driving. I wish I would have known about them sooner. Thank you.

They have made a difference in the handling of each and I am glad I did this. I got them on the Black- Friday sale and saved a lot. They are easy to install and did my motor home in under a hour for front and back. This cost under $400 and the shop wanted around $1800. So each the videos and do them yourself.

My Skoolie feels like I’m driving an entirely different vehicle and not a short bus now. A lot nicer ride and the bus feels more stable.
