About the 4 Inch Lift Kit | X-Series | Jeep Grand Cherokee WJ 2WD/4WD…
Despite its long-standing reputation as an off-road monster and the vast selection of mods available, the Jeep WJ has always been known to suffer in highway ride quality after lifting. Many WJ lifts focus primarily on trail performance, but fail to take in account how the control arms and track bar will perform at their new, lifted angles in day to day driving.
Notes
- Does NOT fit V8 models.
- Does NOT fit models with Quadra-Trac I, Quadra-Trac II, or Quadra-Drive.
- Does NOT fit models equipped with a rzeppa joint front driveshaft.
- Models equipped with a CV style front driveshaft may result in driveshaft vibration. If this occurs, replacing the driveshaft, axle yoke and / or transfer case yoke will need to be performed to rid the vehicle of driveline vibration.
