The Eaton Posi - GM 8.5 10-Bolt 30-Spline differential carrier is designed for serious off-road and street performance applications where traction control is essential. This locking differential replaces the factory open carrier in GM 8.5-inch rear axles, providing positive torque distribution to both wheels during acceleration and cornering.
Constructed with precision-machined components and spring-loaded locking dogs, the Eaton Posi automatically engages when driving torque is applied, reducing wheel spin and enhancing power delivery. Its 30-spline design ensures optimal load distribution and compatibility with OEM and upgraded axle shafts in the 8.5-inch platform.
Ideal for Chevy, GMC, and other GM platforms equipped with the 8.5-inch rear axle, including Silverado, Sierra, and Suburban models from the 1970s to modern production, the Eaton Posi is perfect for enthusiasts and professional mechanics seeking reliable traction without the complexity of electronic systems. Installation requires axle removal for proper fitment.
