To determine if your new lifted truck will fit in your garage, there are two factors to consider: the height of your garage and the height of your new lifted truck. To help you figure this out, there is a formula for determining if your lifted Chevy will fit into your garage. Take the current height of your vehicle, add the lift kit, then add half the tire distance. This is your new overall height. If it's less than the height of your garage, then you are good to go.
