Here you can see the special torsion-bar clamp tool we used for this installation. Essentially, this tool clamps onto the key and crossmember. As it tightens up, it twists the torsion bar away from the factory adjuster nut. The further it twists, the less pressure is put on the factory adjuster. Once all pressure is removed from the factory adjuster, the key can be removed by hand. Next, we simply replaced the factory key with the new ORU units and reversed the impact gun. Once pressure was returned to the factory adjuster, we took ride height measurements and made some further adjustments to dial in our desired ride height.
