GM 8.6" Posi Limited Slip Differential Axle Assembly

The Zumbrota Drivetrain RAA435-2185A-P is a remanufactured axle assembly specifically designed for GM 8.6" 2003-2007 Van 1500 applications, featuring a Posi Limited Slip Differential and a 3.42 gear ratio with a GM 10 Bolt pattern. This axle assembly is rebuilt to high standards of precision and reliability. The remanufacturing process includes thorough inspection and straightening of axle tubes to OEM specifications, as well as testing of housings for surface wear and cracks. Every internal component, such as the ring and pinion, internal gears, clutches, and carrier, undergoes a 100% inspection. To ensure peak performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The assembly is precisely set to the correct rolling torque using inch-pound measurements, and proper gear backlash is established for optimal lubrication and quiet operation. Zumbrota Drivetrain employs an exclusive hydro-blasting and rinsing process for cleaning internal and external parts, followed by a proprietary shot-peening deep cleaning procedure. This method ensures that all housings are returned to their original OEM finish, setting a high standard for remanufactured axle assemblies. Technical notes indicate the ratio is 3.42 with a GM 10 Bolt 8.6 Inch Ring Gear, ratio option GU6, and includes the G80 Posi Traction. It's important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. The product comes with a Yes for cover included, but No for fluid included.
