rear end gear
If you do not have experience with rear ends I wouldn't touch it....would suck to have all that whine early on. I have gm motive 4.10s and I love them. I know they make some great gears so if I were you I would go with a set of gm motive gears.
Supporting mods=tune, stickier tires. You can just get the gears, they are between 180-250, plus you should get the Ratchet delux kit which replaces a lot of the rear end pieces for an additional 220 about.
