The term rim is the shape of a raised edge of a more or less circular object, this can be hoop from which the net is suspended or the outer part of a wheel to which the tire is attached. This is a projection used for strength or for attaching to another object; or either the top edge of a vessel that give more strength or give support to the car.. Nissan 4WD lifts require new wheels. This is because the distance from inner sidewall of inflated tire to rim mount surface cannot exceed 4-1/2", the distance requires wheels to avoid interference. Nissan lifts are complete bolt-on systems that include replacement knuckle adapters.

The job also includes the relocation of the upper & lower ball joints and also the differential drop bracketry and brake line extensions. The Nissan front suspension consists of upper and lower control arms suspended by torsion bars. This a front achieved by adjusting-up the factory torsion bars. As the ride height is increased, the distance between the bottom of the upper control arms and their extension travel stops and decreases. Without extension travel, the suspension cannot do its job of soaking-up the bumps and dips.

The continuous topping out may causes accelerated upper ball joint wear. In some other case, adjusting-up the bars alone is not a real option. To allow sufficient extension travel, the use of super lift replacement tubular upper control arms can help to restore proper ball joint angle, and the camber angle. Nevertheless the amount of lift available will always depend on the pre-lift ride height.
