Overview
The Rubicon Express RE8000M is a 4.5-inch Super-Flex short arm suspension lift kit with monotube shocks for the 1993–1998 Jeep Grand Cherokee ZJ. It is a direct fit for the Base, Laredo, Limited, Orvis, SE, TSi and 5.9 Limited trims.
The Super-Flex system keeps the factory short arm suspension design and uses the factory suspension mounting points.

The specifications list a lift height range of 4 to 5.5 inches and a tire size of 32 inches. The title names monotube shocks, and the specifications list shocks as included.

Tire size and clearance
A 4.5-inch lift raises the body and the axles, which changes how much room the tires have in the wheel wells and at full steering lock. Before choosing a tire size, measure the clearance at the inner fender, the control arm and the steering linkage, and allow for the extra travel the tire needs at full compression. Rubbing often shows up first on the inside of the front tires during a full turn.
Gearing and driveline work usually follow a lift this size. Taller tires change the effective gear ratio, so the transmission may feel strained on hills until the gearing is matched. Inspect the CV joints and the driveshaft angles after installation, and check the steering stops so the front tires do not hit the frame before the stops engage.
