So I have about a $1000 and am taking a chassis fab class in school and need a project. I'm going to use my truck. Right now I have chevys with double shackles and rotating perches in the rear. I like it but would love to go to 4-link and 1/4 eliptic. I also have the all pro hysteer crossover steering installed, and am thinking about using the money on a hydro assist. My question is, which mod would help on the trail more?? I have 35in. bfg's and when aired down they turn, I just have to muscle them. I guess I can't decide which project I would gain more from.
