3.23 Ratio Posi LSD Differential

The Zumbrota Drivetrain Reman Axle Assy is a meticulously rebuilt axle assembly designed for specific GM 8.6" applications. This unit comes with a 3.23 gear ratio, drum brakes, and a Posi LSD (Limited Slip Differential) for enhanced traction and performance. During the remanufacturing process, all components undergo rigorous inspection. Tubes are straightened to OEM specifications, and housings are tested for surface wear and cracks. Internal parts, including ring and pinion gears, internal gears, clutches, and carriers, are inspected 100%. To ensure longevity and proper function, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced, and the correct rolling torque is established using precise measurements. This axle assembly is built to order and ships when ready, with options for expedited shipping. A refundable core charge applies, which is returned upon receipt of your old, salvageable part. The product is designed for 2005-2007 Chevrolet Silverado models with drum brakes and a Posi LSD.
