Ok my blazer is lifted and I have no idea what size lift it has. The guy I bought it from told me he couldn't remember what size he put on. But the problem I'm having is it has 38.5" tires and everytime I take a turn they rub real bad or atleast use to. What size lift should I have on it so the 38.5" fit correctly? My buddy's brother has a lifted 87 Sierra show truck that runs the same size tires, my buddy told me I need atleast a 12" lift to fit my tires. I have the Super Swampers TSL Boggers (like the off-road use 1's) Can anybody help me out. And here's some pics of my truck maybe they will help tell what size lift I have. http://s201.photobucket.com/albums/a...lazer%20truck/

 

Nice truck. My brother has 39.5's with a 3" body lift and I think about 8" of suspension lift. No rubbing issues.

 

it depends on your creativity. I have a 6" lift on my k5 and I am running 39's. Slight mod to the wheelwell, but nothing drastic. just rounded the edges a little
