Even after replacing the rear shocks, my 1999 Astro still needed something to help with the rear end leaning off the highway with tight corners... Thought it might do with a sway bar after sale give...well I went for these spring assisted shocks and what a big difference, it's 1 1/2 inches tall and handles tight corners very well with no pitch or body roll. My trailer pulls much better with no rotation…. worth the price, much cheaper and easier than a stabilizer. The first photo is a day before replacing the shock absorbers, the second photo is a minute after the replacement! It took me a good 30 minutes to swap out both.
