South Bay Truck built a Ford 9-inch with Currie 31-spline axles, disc brakes, and a Detroit Locker. The axles use 5.29 gears to put more torque to the 33-inch BFG Baja T/A tires.
Dual Fox 2.5 shocks reside on either side of the third member. This might seem like a lot of shock but Frank has had Fox valve them to work in conjunction with the weight and spring rate of the rear Deaver leaf springs.
Link also built traction bars with rod ends to prevent the Deaver leaves from wrapping while racing.
A 22-gallon fuel cell sits in the back of the rear axle along with dual Optima Yellow Top batteries.
