Underneath the rig is a custom crossmember/skidplate made from 1/2-inch plate, 1 1/2-inch square tube, and 1/4-inch plate. It helps protect the school bus-sourced SM420 four-speed transmission that was bolted to the engine via an Advance Adapters adapter, as well as the Dana 20 transfer case. The Dana 20 has been fitted with Dana 18 gears. The benefits of these gears include a low range ratio of 2.46:1 instead of the stock 2.0:1 ratio.
