On the final day we hit the St. Anthony sand dunes. Lonnie McCurry Jr. of West Monroe, Louisiana, aired out his '07 JK Unlimited Rubicon rolling on a Skyjacker 4-inch Rock Ready long-arm lift kit. The Jeep sports a 6.1L Hemi, five-speed auto tranny, and the factory T-case. The Rubicon Dana 44 front and rear axles feature 4.88 gears. RCV shafts got the nod up front and Alloy chromoly shafts were stuffed in the rear. It all rolls on 37-inch BFG Krawlers mounted to 17x9.5 Raceline beadlock wheels.
