the kit will come with everything u need for the rear. new hangers and shackles for the leaf springs. any blocks and pinion shims can come out. shims may need to be adjusted. for the front it comes with the lower control arm in the kit. just need to put in a stock upper. other than that fix the diff. put the diff as high as u can. stock location is ok but if there is anyway to go a slight bit higher than stock it will be good. my cvs have a slight angle up. still launches straight without a problem though.
