Thanks guys/gals, Here's the heads up of the progress so far. Wifey surprised me that we'll be having a baby. Time to cut down the project a little bit. Thinking of going 3" lift for now with spindles and blocks and adding stainless steel brake lines. Do I need to change gears with 32" tires with stock rims instead of 33"? Also I'm having what the guys at Off Road Warehouse telling me whats called a power surge, When I'm on the highway and it act like a wind resistance pushing the truck a bit but it's just either motor or gears hesitation. The ORW guys said it's very common with our trucks. Since y'all have owned and still owns the beautiful General Motor/Chevrolet SUV and may come across this problems, Please give me a heads up to look at what I need to get to fix this "power surge".
