The Zumbrota Drivetrain RAA435-1579A is a remanufactured complete axle assembly designed for the Dana 60 rear end. This axle assembly undergoes a rigorous inspection process, checking for straightness, cracks, and surface wear. Internal components, including the ring and pinion, gears, clutches, and carrier, are thoroughly inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are set for optimal tooth contact patterns and rolling torque, measured in inch-pounds, ensuring proper lubrication and quieter operation. Features include an axle type of Full Floating, a included cover, and new bearings and seals. The ring gear diameter is 9.75 inches, and the axle rating is 6200 lbs. This assembly comes with a 3.55 ratio and Posi-LSD. Fluid is not included.
