| 2007 Ford Explorer Sport Trac suspension Installed
In the past, we have always given our readers a look at the best SEMA feature trucks present at the show. For a change, we thought we would give you a sneak peek of what it takes to build a feature-worthy truck for SEMA.
In the previous build-up tech articles, "One for the Show," Parts 1 and 2, we teamed up with Casey and Ron Scranton of CGS Motorsports in Pomona, California, as they brought the Sean Smith rendering of Coppertone to a reality. The '07 Ford Sport Trac would receive a custom-built aero body kit by Elahn Industries, Top Shop in Corona, California. Casey and Ron shaved the door handles and antenna.

The Sport Trac's entire exterior surface was given a primer coat before Jeff Meech, from Crazy Customs in Escondido, California, applied multiple coats of BASF Coppertone color. It was then given four coats of clear. After the newly painted skin was given a day to cure, it was cut, buffed, and polished by Jake King, a 3M tech specialist and Jerry Berns. A dry, color-sand technique was used, instead of the traditional wet-sand technique. 3M Perfect 3,000 rubbing, buffing, and polishing compounds were then used to bring out the depth and incredible glistening finish.
This segment of "One for the Show" Part 3, will showcase the suspension, wheels, and tires. Casey and Ron wanted to lay out (airbag) the Sport Trac's unique front and rear independent suspension. An Air Lift pneumatic 'bag system with computerized, self-leveling capability was installed at CGS. Then, the Sport Trac Coppertone was trailered over to Devious Customs in Riverside, California, where Jeff Davy and his crew installed the compressor, airline manifold, 1/2-inch-diameter airlines, computer, storage tank, digital controller, and electrical systems. A custom diamond-plate platform and mounting frame were fabricated to house the Air Lift compressor, airline manifold, solenoid valves, relay, computer, and valves that were located in the spare tire space, which is under the bed and behind the rearend. The Air Lift 5-gallon air tank and mounting brackets were welded to the rear crossmember behind the rear end. The 1/2-inch-diameter front and rear airlines were then fitted into the compression choke fittings. The CAT 5 cable was connected to the hand-held electronic control unit (ECU) that was stored inside the center console for easy access. The quick-fill system would recycle itself for instant intake and exhaust of the Air Lift system.

The Pirelli Scorpion Zero 265/35ZR22 front and 305/35ZR22 rear were then mounted onto a set of one-off Devious Edge 5 22x8-inch and 22x9-1/2-inch aluminum wheels. Brian Doyen at Hot Motorsports in Santa Ana used a Corghi tire-mounting machine, which delivered both agility and strength for mounting tires with low-profile sidewalls on large diameter wheels, to mount the new tires onto the wheels.
After the wheels and tires were mounted on all four corners. The Air Lift system was then activated, which sparked the compressor, and filled the 5-gallon storage tank to its capacity in a few minutes. After the compressor shut off, Casey purged the system, which instantly descended the Sport Trac to earth, tucking the 22s up inside the wheelwells. The control panel was then activated and instantly popped the Sport Trac up on all fours to its pre-programmed ride height.
From The Driver SeatWe idled around in the parking lot to make sure there were no surprises. As we pulled out of the driveway and accelerated down the road, the Sport Trac's ride was like floating on air-no pun intended. As Casey applied the bakes and rolled into a corner, the front and rear independent suspension and the Pirelli Scorpions dug in and gripped the asphalt with limited body roll. Coppertone felt like it was on rails. The overall ride was very good. After we cruised into the parking lot, Casey put it in park, purged the 'bags to the pre-programmed layout specs, dropped Coppertone's framerails within a 1/4-inch from the asphalt, tuckin' those 20s and 22s. It was too cool.
