I just bought my 81 Blazer from a guy who said he thought it had a 4" lift. I'm not sure if I believe him because it has 35" tires with a lot of clearence. It has more clearence and feels more top heavy than my friends 72' with a 4" and 33" tires. Can anyone tell me how to check and where to measure for lift height. I'm pretty sure it doesn't have any body lift. Please help.
