From inside the cab, intake air is routed through this piping to the UMP airbox that feeds the engine.
The beefed 2WD front axle was mounted during Day 7 using Skyjacker lift-kit pieces and hefty Currie steering linkage.
With the axle in, it was time to work on the steering. Krellwitz and Jason Rivera plot where to mount the tilt-steering-column mechanism in the cockpit. The steering shaft looks like it could be shortened just a bit.
The interior layout is also far enough along that the seat mount brackets can be welded in place.
The rollcage's rear downbars were welded in on Night 6 so that the framework for the rear bumper/spare-tire carrier could be fabricated on Day 7. You can see one of the 33x10.50R15LT BFGoodrich Baja T/As that'll be used on the Jeep as well as the two new battery brackets, located just ahead of the rear wheel tubs.
Also on Day 7, the crew mounted these subframe bars, which tie the front and main hoops together and also reinforce the front spring mount points.
LaFortune works on hanging the leaf-spring shackles, which were TIG-welded for extra strength.
