Remanufactured Axle Assembly 3.73 Gear Ratio

The Zumbrota Drivetrain RAA435-2064 is a remanufactured axle assembly engineered for 1998-2003 Chevrolet S10 ZR2 models equipped with the GM 8.5" rear axle and a 3.73 ratio. This assembly is rebuilt to stringent quality standards. The remanufacturing process involves a comprehensive inspection of all components. Tubes are verified to be straight to OEM specifications, and housings are meticulously tested for any surface wear or cracks. Internally, every part, including the ring and pinion, gears, clutches, and carrier, is subjected to a 100% inspection. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are also cleaned using a state-of-the-art hydro blasting and rinsing process, restoring them to an OEM finish. A precise rolling torque is established using inch-pound measurements during setup. This product is built to order and includes a $400 refundable core charge, which is returned upon receipt of your old, salvageable part.
