This is for the serious off-roader. We designed this kit to be used with our bed cage system for maximum useable wheel travel. For the most part this kit bolts on but there is minor fab work and welding involved. The benefits of going spring-under with the leaf springs is more wheel travel, faster rebound and articulation from a leaf spring pack that has more arch without lifting the rear too much, a more progressive design for better bottoming control and reduced axle wrap.
