UL­TI­MATE COM­PETI­TOR

Diesel World - - Feature -

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.

 Lenny Reed and Don­a­van Har­ris (cen­ter) ac­cept the sec­ond place UCC sled pull tro­phy from Al­li­ga­tor Diesel’s Chad Hall.

 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.
