is handed off to a set of factory driveshafts to deliver the power to the stock AAM 9.25 axle up front and the stock AAM 11.5 axle in the rear. Yukon Gear and Axle gears in various ratios (the exact numbers kept secret) for each event Harris runs are stuffed into each axle assembly. During drag racing and dyno competition he runs the factory differential and axle shafts in the front axle with an Eaton locker and stock axles in the rear. For sled pulling, the Armor Inc. team swaps out the front differential for an Eaton Detroit Truetrac differential with Yukon gears and axle shafts. In the rear they swap out for a Yukon spool, gears and 38-spline axle shafts.
Putting the power to the drag strip, dyno rollers and pull track is highly important if you aim to win diesel competitions, so Harris has a wheel and tire combination for each discipline. When he’s hitting the dyno rollers the truck typically sports Moto Metal wheels wrapped in 305/50R20 Cooper Zeon LTZ tires. For drag race competition the Armor Inc. team swaps out the tread for a set of 16-inch M&H drag slicks mounted on Raceline wheels for great traction and light weight. To handle the slick dirt surfaces of sled pulling the team mounts up a set of six 35/12.50R17 tires on Fuel wheels with four Interco Truxus tires in the rear and a pair of Nitto Mud Grapplers up front.
Continuing with the weight reduction theme, Harris and the Armor Inc. build team stripped the cab of the factory seats, door panels, side and rear windows, dash, headliner and other trim, leaving the factory carpet as one of the only remnants of the truck’s original interior. For safety at the high speeds the truck would be capable of running, they fabricated and installed an Nhra-certified 7.99-second rollcage using chromoly tubing. The cage ties into the factory frame below the cab and in the bed to strengthen the entire chassis and protect the driver. The factory windshield remains in place, but the side and rear windows were replaced with lightweight acrylic windows to save weight and allow the rear tubes to run through the rear window into the bed.
The team installed a new lightweight aluminum fabricated dash panel complete with their “Say No To Slow” motto cut out of the top of the dash panel. Aluminum panels also replace the factory door panels, along with removal of the factory glass and window regulators for more weight savings. The bulky and heavy factory steering wheel and column was replaced with a simple column and Driven race wheel on a quick-release hub. With the factory steering column and shifter gone, Harris installed a B&M shifter on the floor to run through the gears on the track. To datalog his passes and keep the driver informed at a glance, a TS Performance Informant Pro system and an analog Autometer Ultralite II boost gauge were installed. Harris sits comfortably in a Corbeau race seat and is held safely and securely in place with a 5-point G-force Racing Gear harness. The cab is also home to the Snow Performance water/methanol tank and pumps as well as the Nitrous Outlet nitrous bottle.
Harris tells us that, as with most truck projects, he isn’t finished with this one. After placing well in the UCC rankings for the first two years, Harris and Reed made another strong showing at the UCC 2018, taking fifth in the sled pull and fourth at the dragstrip with an 8.58 elapsed time. Something tells us we have still not seen the last of this truck.
We caught this shot of Harris blasting down the famous Lucas Oil Raceway drag strip in Indianapolis during the 2017 UCC, where he finished fourth overall with a third place finish in the drag race portion of the event.
With extra weight hanging off the front end and grippy Nitto and Interco tires wrapped around Fuel wheels, Harris and his team converted the truck from a fast drag racer to a stout sled puller to finish in second place on the pull track in the 2017 UCC.
From the passenger side of the truck, the Nitrous Outlet nitrous oxide bottle and Snow Performance water/methanol injection tank and pumps dominate the interior, along with a B&M shifter for Harris to bang through the gears as he flies down the strip.

From the driver-side door, the competition purpose of Harris’ Dodge is once again evident with the Nhra-certified rollcage and all the necessary safety equipment for high-speed racing duties. Notice the aluminum interior panels and bolted-in acrylic safety windows that help reduce weight over using the factory components.
