We knew this one was special the moment we first spotted it at the 2024 Grand National Roadster Show. Now it’s official—the 2025 SEMA Battle of the Builders Presented by Mothers Polish has crowned Troy Trepanier of Rad Rides by Troy as the best overall builder of the year with his jaw-dropping Fenderless ’36 Ford Roadster.

A Tale of Two Tensioners

This is a story about two tensioners, one fabricated with machine tools and the second fabricated in a garage with a minimum of tools. In fact, the only power tool you will need is a drill motor, yet the finished products will be almost identical.

Your first response to fabricating something may be, “I don’t have the necessary tools; I don’t have any way to get the materials I will need.” If you have a door number so the UPS man can find you, you have everything you need. The materials list at the end of this story contains everything you will need. The rod-end bearings and lock nuts were purchased from AFCO Hot Rod Parts. The aluminum round stock and cutting tools were purchased from MSC.

Jeepspeed

Between 1984 and 2001, Daimler Chrysler built about two million eight hundred thousand Jeep Cherokees. They were built in several combinations—two and four door, two and four wheel drive and stick or automatic and with three different engines. The vehicle was not well received. In print they were tagged as being too long, too heavy, under powered, poor brakes , and worst of all—uni-body construction. Before every Tom, Dick and Mary had an SUV in the driveway, young families were getting to work, going to school and having weekend fun. Give credit to Jeep for introducing a lot of young people to off-roading thru the Cherokee line.

ON THE LEVEL

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.
