The practice modifies a specific sport utility vehicle model from a particular year by elevating the vehicle’s body relative to its frame. This alteration involves installing spacers or blocks between the body and the frame, creating additional clearance without affecting the suspension geometry.
This modification can provide increased tire clearance, enabling the use of larger tires for improved off-road performance or aesthetics. Furthermore, it can offer a less expensive alternative to suspension modifications for achieving similar height gains. In the late 1990s, this type of alteration gained popularity within the off-road enthusiast community seeking to enhance vehicle capabilities and appearance.
