I like these shocks for the way they ride and help with towing. If you want to install them yourself, please be patient. There wasn't much room in the left rear of my Suburban for these shocks. Due to the increased diameter at the top of the shock to accommodate the spring, installing the top mounting bolts can be tedious but doable. I use my Suburban to tow trailers, as a heavy duty station wagon, and for a lot of traveling. With a range of 2-3 thousand kilometers, they worked well.
