I own a 04 crew cab silverado z-71... Ive had the truck for three years and I want to start modifying it. I want to run 20's on it with 33"s or maybe a little smaller. I was thinking bodylift to 2 to 3 inch. I dont do a whole lot of mudding in it.. I hate spending all day under my truck cleaning mud out. im sure alot agree with that. ON the other had i was thinkin about blockin the back and raise front, but would that be enough for bigger tires .What would be the cheapest and durable way of lifting my truck... any advice on what to do...
