I'm not an expert on shock absorbers but I like them. To be honest I bought them because they're black, they sizes up have for my truck with a different height and cost less than $20. They fit the back of my 1985 Toyota pickup truck with 2" lift. Now the truck is definitely more comfortable to use and the fluid doesn't leak. Bilstein or I couldn't afford OME shocks, so they seemed like a good middle ground.
