One way of adding height to your sports utility vehicle or pickup truck is to install Skyjacker blocks in conjunction with add-a-leaf springs. These blocks can be stacked on existing blocks or installed by themselves to raise the back end of your vehicle. Lift blocks vary in height which may range from 1.5 inches to 5.

5 inches. Lifting the height of rear end of your vehicle is important not only with respect to aesthetics but also important in terms of providing enough space between the axle and the chassis. The space is necessary in maintaining the optimal function of the rear suspension system. Lift blocks allow the rear end of your vehicle to gain extra height without jeopardizing ride comfort.

Skyjacker blocks are made entirely from ductile iron with fixed center pin. Ductile iron, owing to its malleability, has greater capacity to absorb shocks and compression. Hence, it is an ideal material for a suspension component. The lift blocks are tapered specifically on the type of vehicle to correct the angle of the pinion and prevent driveline vibrations. These lift blocks are perfect for leveling out the worn and sagging leaf springs of the rear wheels. They are easy to install and includes U-bolts and associated hardware. There are several important rules to remember regarding lift blocks. First, never use lift blocks on the front end of your vehicles because this is dangerous and may cause the collapse or instability of the steering suspension. Second, you should never try to stack more than two blocks on top of each other for this may also collapse or result in the instability of the rear suspension. Third, you should avoid more than 6 inches additional height from lift blocks to prevent severe axle wrap.
