Masterclass in Metal: The Battle for the Al Slonaker Memorial Award
The 75th annual O’Reilly Auto Parts Grand National Roadster Show, presented by Meguiar’s, went full throttle this year, bringing out some of the most insane custom cars the hot rod world has ever seen. Sure, the AMBR award gets all the press, but the real hardcore builders know that the Al Slonaker Memorial Award is where true engineering battles happen. This isn’t just about looking pretty—this is about pushing the limits of fabrication, design, and flat-out mechanical genius.

Product Spotlight: DIESELSITE 17-Row COOLERMAX Transmission Cooler
Rated at a monster 59,000 BTUs, this cooler doesn’t just compete—it sets the bar. Standard factory units limp along at 15k–30k BTU. Even most “heavy-duty” aftermarket coolers top out well below the COOLERMAX’s rating. That extra capacity can mean the difference between cruising safely at 180° or cooking at 240°. In the real world, that translates into drops of 50–60°, longer fluid life, and transmissions that simply last.

DJM Engineers a Leveling Kit for the 2007 Tahoe

The ’07 Tahoe, Chevrolet’s premature baby, hit the street in late March 2006. Introducing the next generation of Tahoes so early was part of some master marketing scheme, born and nurtured in the hallowed halls of Chevrolet corporate. In any case, the ’07 Tahoe’s rear ride height measured 23-1/8 inches from the center of the hub to the lip of the fenderwell, while the front measured only 20-1/4 inches. As usual, the rear stood considerably higher than the front.
For those who don’t see this suspension configuration as “cool,” DJM Suspension of Gardena, California, a manufacturer of suspension lowering kits, immediately set to work engineering a leveling kit to put the “ass-end” of the ’07 Tahoe on the same plane as the front. In other words, DJM engineered a cool-looking kit.
The DJM leveling kit features 2-inch rear drop springs, for which the installation is rather straightforward.
After the wheels are removed, the lower shock mounts are unbolted. The sway bar is then unbolted but not removed. The rubber isolators are removed and saved to be re-installed. The 2-inch rear drop springs are then installed. When the springs are securely in place, the lower shock mount is rebolted. The sway bar is then retightened in place.
At the completion of the DJM leveling kit installation, the rear had been brought down exactly 2 inches and its ride height measured 21-1/8 inches. The installation of the DJM leveling kit made all the difference in the world to the stance of the ’07 Tahoe.
The accompanying photos follow the highlights of the teardown of the stock suspension and the installation of the DJM lowering springs. Check it out if you are looking for that cool stance on your new Tahoe.
