The exterior sports a modest number of modifications. Up front is a lightweight Mopar MPG bumper that is made from a 10th Anniversary Rubicon front bumper. Protecting Slim’s rockers are a pair of modified Mopar rock rails that have been lightened by strategically removing circular segments. Other exterior touches include a black grille, black hood decal, prototype LED headlights, Mopar taillight guards, Mopar locking gas cap, Mopar 17x8 five-hole Classic wheels, and LT35x12.50R17 General Grabber tires. Slim is powered by a 3.6L V-6 engine (with Mopar cold-air intake) mated to a five-speed automatic transmission. A 4:1 ratio Rubicon-sourced Rock-Trac transfer case splits power to the axles.
