After spending a week in Moab with the innovative people from Burnsville Off-Road, we had to bring you some of the vehicles we 'wheeled with that week. You've already seen a few of them in the magazine, and there will be a few more featured soon. The flagship of all the Burnsville Off-Road vehicles at Moab this year had to be 40-Something, Dan McKeag's Viper Snakeskin Green 2007 JK Wrangler. It's named 40-Something because of its 42-inch Irok tires and because Dan thought it was a good counterpoint to the other flagship vehicle they built for Mopar Underground, the Lower-40 JK roadster.
While Lower-40 runs 40-inch tires with no lift and lots of trimming, 40-Something runs big, 14/42-17LT Interco Irok bias-ply tires along with 3.5-inch coils from Currie Enterprises. Currie was also tapped for a pair of its excellent RockJock 60 front and rearends. The beefy RockJocks were needed not only for the 42-inch Iroks, but to handle the power of a Mopar 392 Hemi V-8 crate engine. A Mopar 5-45RFE multi-speed automatic transmission was installed behind the 392. An Advance Adapters Atlas two-speed transfer case is bolted behind the tranny and affords a super low 5.0:1 low range.
The parts used to build 40-Something are impressive and the bodywork on this JK is, too. The roll cage is a custom design and the steel flat fenders are completely hand built. The custom work allowed the rearend to be moved back 4 inches, using Currie front lower control arms in back with a single torque arm for the upper rear arm. An AEV hood keeps underhood temperatures down and, as we already mentioned, the JK was painted Viper Snakeskin Green.
Peruse the photos. We think you'll agree that this is one fine Jeep.
