Well I purchased a set a rear Timbrens for my truck. After one week of testing, I decided to return them, here is why. Extremely easy install, that's a given. They absolutely minimized the rock...
I like the ones I installed on my f150. I don't mind the bounce at all. I spent $200 dollars on them and they cured all my problems. I don't recommend to people overloading a half ton the way I did. But if you want a quick fix without spending a ton of money they will take care of the sway, and the squatting your truck in the rear. When I sale my f150 they are coming off and going on my 12 valve.
