The front axle is a kingpin-style Dana 60, pirated from an ’83 Chevy K30 military ambulance, and it’s equipped with a Detroit Electrac locking differential, Precision Gear 4.56 gears, an eBay-sourced diff protector, Yukon 4340 chromoly axleshafts, and Yukon manual locking hubs. The axle is located laterally via a custom track bar made from 1.5-inch-diameter, 0.250-inch-wall material with Currie Johnny Joints at each end. The bar is affixed to custom mounts. The steering setup utilizes an Offroad Design pitman arm; WFO Concepts Heavy-Duty Crossover Steering Kit; C&M Performance Machine AMPCO bronze alloy kingpin bushings; ORD tie-rod ends; Offroad Design drag link; and custom tie rod made from 1.5-inch-diameter, 0.250-inch-wall tubing. A PSC ram-assist steering system makes pointing the big 37-inch tires a no-drama event.
