The Zumbrota Drivetrain RAA435-2239B-P is a remanufactured axle assembly specifically built for 2005-2007 Chevrolet Silverado and GMC Sierra models equipped with the GM 8.6" rear axle. This unit comes with a 3.73 gear ratio, Posi Traction for enhanced grip, and is set up for drum rear brakes with the JF3 option. Each axle assembly is meticulously remanufactured.

To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is thoroughly cleaned using a hydro blasting and rinsing process, restoring it to an OEM finish, and precise rolling torque is established through inch-pound measurements for maximum precision and longevity. This remanufactured axle assembly is built to ensure an exact fit, directly replacing your original axle assembly. The product is built to order and ships when ready.
