Northern Tool & Equipment supplied a set of Ultra-Tow spindles and hubs for the project. They’ll be paired with a 2-inch x 0.120-inch-wall tube to become the new axle. The existing axle was too narrow to fit the desired tire and wheel size. The Northern Tool & Equipment Ultra-Tow spindles are manufactured from premium high-tensile strength steel and are rated at 1,750 pounds. The Ultra-Tow hubs are preassembled and pre-lubed with premium grease. They’re constructed from ductile cast iron for higher tensile strength, less deflection, and excellent corrosion resistance, and are electroplated to resist rust and corrosion. Each hub includes a bearing cup, lug studs, bearings, and seal installed, as well as the dust cap, dust cap installation tool, cotter pin, and lug nuts. The hubs are rated at 1,750 pounds and feature a 5 on 4 1/2-inch bolt circle.
