During a recent resurrection and beautification of his faithful ’01 Tahoe, the customer sought a very mild drop to achieve a more attractive, aggressive stance. At the customer’s favorite accessory shop, FA Motorsports in Huntington Beach, CA, owner Andy Barger suggested the installation of DJM’s 2X3 drop kit which lowers the front by re-indexing the torsion bars with new torsion bar keys.
“This DJM kit drops the front with torsion bar keys and the rear with coil springs,” explains Barger. “Frankly, it is an easy install and it is relatively inexpensive for the customer. This guy didn’t want to put his Tahoe in the weeds. He simply wanted a mild, inexpensive drop that would leave his vehicle with a more attractive stance. And most importantly, all the reports we’d ever heard on this 2X3 DJM kit and our own testing indicated that the stock ride quality was retained after the installation.”
Unfortunately, the installation of a new, frame lift at FA Motorsports had not been completed by the time the Tahoe was to be lowered. Therefore, the install had to be accomplished on the company’s platform lift. Although installer Josh Bailey got the job done quickly and efficiently, the installation of the DJM drop kit would have been considerably easier on a frame lift.
The Tahoe went from 21 inches in front before the install to 19 ½ inches after the install, a drop of 1 ½ inches, and from 22 inches in front to 18 inches, a 4-inch drop in the rear. And as we anticipated, the stance was greatly improved and the ride quality and handling were not adversely affected.

This DJM kit includes torsion bar keys for the front, coil springs, trailing arm brackets and swaybar end-links for the rear. All the hardware you need, with instructions[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_02.jpg]21360Before Measurements
It is important to measure and record the ride height measurements of your installation before you begin. It gives you a baseline to compare your measurement after you've finished and it can make you aware of any irregularities you may have right from the top. The best way to measure is from the center of the wheel to the lip of the fender well [img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_03.jpg]20760Rear Swaybar
Loosen and remove the swaybar end-links, then loosen and remove the hardware for the pivot bushings[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_04.jpg]19940Remove the Bar

Using a standard issue hack saw, the factory bumpstops were shortened to allow a little more travel[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_12.jpg]19880A Cut Stop
This is what the bump stop looks like after the mod[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_24.jpg]19230Install the stop
Install the modified bump stop in it's original location[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_13.jpg]20220Shock Mounts
It's time to attach the lower shock mounts and secure the springs in place[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_25.jpg]19190Install the Bar
Now that everything else is installed and secure it's time to install the swaybar using the new shorter end-links included with the kit[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_14.jpg]19150Wheels back on

Here the torsion bars tension (or load) is being relieved or lightened on the passenger side in order to get to the factory "key"[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_18.jpg]20860Torsion Bars
Same for the drivers side[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_19.jpg]19810Preparing to remove
Josh raises the front slightly with a "bottle" jack[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_20.jpg]20270New keys installed
He then removes the stock torsion bar keys and re-indexes the torsion bars with the new DJM torsion bar keys.[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_22.jpg]19830After Measurements
Measuring the new ride height indicates a drop of 1 ½ inches in front and 4 inches in the rear.[img src=http://calmaxsuspension.com/wp-content/flagallery/2001-tahoe-23-torsion-key-drop/thumbs/thumbs_23.jpg]19920
The DJM lowering kit resulted in a mild "normal driving style" drop, the '01 Tahoe exhibited a greatly improved stance and retained its ride quality exactly.
