2005-2009 Dodge Durango 2WD and 4WD Part #66-1080 Torsion Key Installation

Step 1: Prior to lifting the vehicle it is recommended that you measure the stock height so that you have a base line measurement. Measure from the bottom of the wheel to the lip of the fender, as in Insert A.
Position vehicle on a flat surface and lift vehicle by the frame so that the front wheels are off the ground. Use a floor jack and jack stands or a (2) two post lift if available. Next, locate the torsion key at the rear of the torsion bar under the cab of the vehicle.
Step 2: Remove the torsion key adjusting bolt completely. Using a GM Torsion Bar Unloading Tool (ReadyLiftŪ 66-7822A recommended), and the bracket supplied in the ReadyLiftŪ kit as shown in (Insert C)
Compress the key so that you can remove the threaded part of the torsion adjuster. Releasing the tension on the unloading tool will now release the tension on the torsion bar.
Slide torsion bar forward, allowing the torsion key to be removed.
Step 3: Install the ReadyLiftŪ forged torsion key and slide torsion bar back into position.
IMPORTANT! Make sure torsion bar is extended at least ž” through the torsion key. Apply pressure with torsion bar unloading tool to the torsion key, and create enough space to reinsert the torsion key keeper that the adjusting bolt threads into.
