Rule No. 4: Build a truck that works—something with power, big meats, a realistic lift, strong axles, low gears, and workable parts. For the underneath components, Boone has a front 10-bolt axle, a rear 14-bolt axle, 4.10s front and rear, and extended driveshafts. No lockers…yet. Suspension is moderate but capable in the 8-inch Skyjacker style.
