Description

This unit is built for GM 10-bolt 8.5-inch ring gear applications, specifically for 1995-1999 GM Suburban 1500 models with a 3.42 gear ratio and 5-lug axles. It features a Posi Limited Slip Differential (LSD) for enhanced traction. Each axle assembly undergoes a rigorous remanufacturing process. All tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internally, all parts, including ring and pinion gears, internal gears, clutches, and carriers, are 100% inspected. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are cleaned using a state-of-the-art hydro blasting and rinsing process to achieve an OEM finish. Furthermore, correct rolling torque is precisely established using inch-pound measurements for optimal setup and extended service life. Technical notes specify that this assembly includes the 3.42 gear ratio, GM 10 Bolt 8.5 Inch Ring Gear, 5 Lug Axles, and the GU6 ratio option with G80 Posi Traction. However, it explicitly does not include hubs, brakes, backing plates, or axle shafts.
