Making its second appearance at TTC, this ITL front steering SD-70 axle is rated at seven tons gross axle weight and 10,300 lb-ft of torque. For good measure, there is a set of 7:1 ring-and-pinion gears in the diff. Additionally, there's a set of 5:1 reduction gears in the hubs, giving Barker a 35:1 crawl reduction in the axles alone. For front suspension, the rig employs a four-link arrangement that includes 16-inch King coilovers and Evolution rod ends with King pneumatic bump stops.
