This is my 2001 Silverado 2500HD, with a 6.0, auto and 4.10 rear end. I am running the 6" Rancho lift with a Superlift 5" block in the rear. I am running 36x14.50x16 Swamper STS's on 16x10 Eagle Alloy 102's. As far as under the hood, not too much. Got a K&N FIPK, Throttle Body Spacer, Taylor plug wires, Flowmaster 50 Series Dual in/out and a Westers Custom Tuned ECM.
