Hey guys, looking for ways to improve the traction on my '86 shortbed GMC pickup. Stock suspension, 400 rwhp, beefed up 350 transmission, probably 3.08:1 rear gear. I don't plan on racing this truck just would like to be able to accelerate away from a stop light without breaking loose the rear wheel. A posi unit is definitely in my future. If I move the leaf springs mounts to the bottom of the axel housings instead of the stock positions on top will this help transfer the weight?
Thanks for any information.
