B1 Body Lift; Formed urethane spacer system; Raises body 1.25 in. on chassis; Fits between vehicle body and OE body mount; Includes grill supports; Bolt-on; Kit As opposed to raising the vehicle chassis in relation to the axles, a body lift consists of puck-shaped spacers that raise the vehicle body in relation to the chassis. Because the suspension is not altered, a body lift does not affect spring rate or suspension geometry. Furthermore, its effect on the vehicles center of gravity is minimal since the chassis and drivetrain height remain unchanged. Unfortunately, there are many body lifts on the market that are poorly designed and unsafe for off-road use. Consumers should be aware that inferior body lifts can fail when exposed to harsh off-road conditions, which may leave the vehicle immobilized. 1 Installation of 1.0 in. motor mount lift [JKS PN: 8100] is strongly recommended to re-align engine fan with shroud.
