Download Tools required for installation: To install these leveling keys you will need access to a good hydraulic floor jack and jack stands, a GM style torsion bar unloading tool, (or similar puller) and a metric socket / wrench set. The total time required to install these keys is generally less than two hours. If you live in the “rust belt” it is a good idea to apply rust penetrant onto the keys / adjusting bolt and torsion bar HEX shaped areas before beginning to make removal and installation easier. Will my vehicle need to be aligned once it has been leveled? The answer is YES! The front end alignment MUST be checked and adjusted as needed once the leveling keys have been installed. Most vehicles will require a slight toe adjustment (increase toe in) to ensure your alignment is as the factory intended it to be. We recommend for those that install the leveling keys at home to have the alignment checked as soon as possible to prevent any uneven tire wear or poor vehicle handling. 1) PREPARE VEHICLE…Park vehicle on level ground. Put transmission in neutral, set parking brake, and chock rear tires. Using a hydraulic floor jack, raise the front of the vehicle enough to get the front tires off the ground. Secure a jack stand beneath each frame rail behind the lower control arms. Ease the frame down onto the stands and place transmission in PARK. Check to make sure the rear tire chocks are in position.
