i guess i meant for my control arms and sway bars, since i will be under their anyway

i was trying to find 4 inch drop leafs for the rear, i think i found some. but they are like 315 for both, and i dont even know if they are 4".

i went on mcgaughys website to look at thier spindles. and they have the 2" spindles on their http://www.mcgaughys.com/truck_new.html so thats where im probably gonna order them

also what are the differences in handiling/traction between the 4" shackle and hanger kit and just the 4" drop leaf for the rear? i mean if there arent many drawbacks for the shackle hanger kit i think i would rather just spend less money and not worry about more work when i have to grind out the rivets from the factory hangers.

also, i heard somewhere that you have to use shims on the driveshaft so that if you do intend to burnout/race it, you need it so you dont have wheel hop.
