A body lift is a common and cheap method to run larger tires on a vehicle. It involves installing a puck where the body mounts to the frame in order to increase the clearance between tires and the body. This is often used to allow the placement of a larger motor for an engine swap. It is considered by many to be inferior to a well built suspension lift. The downfall to installing pucks for spacing is that over time the rubber in the puck tends to deteriorate. This causes the body to sag, and will eventually become unsafe. While the controversy continues about body lifts versus suspension lifts, a properly installed aftermarket body lift kit can give the desired effect just as safely as a suspension lift.
