A lift kit is designed to increase the space between the vehicles suspension and its frame, or between its body and its frame. Lift kit gives the vehicle additional ground clearance and suspension travel. It also gives space in order for larger wheels and tires to possible fit under the vehicle.

Lift kits may include blocks, add-a-leafs, coil spring spacers, lifted spindles, replacement control arms, and special brackets for mounting suspension components lower on frame. It may also give your Jeep Grand Cherokee a bolder look. Aside from that, more ground clearance will protect your vehicle from high bumps to brush on it. However skid control might be affected.
