Features and Benefits
Remanufactured to OEM specifications for the GM 11.5-inch 14-bolt rear axle platform — delivering a direct-fit replacement with correct geometry, bearing preload, and gear mesh.
3.73 gear ratio with Posi-Traction limited-slip differential provides controlled, bias-balanced power delivery to both rear wheels — essential for towing and hauling on 2500 HD applications.
US Powertrain engineers identify and correct known OEM design deficiencies during the remanufacturing process — resulting in a unit that can outperform and outlast the original equipment it replaces.
Differential cover included — no additional component sourcing required for a complete, ready-to-install rear differential assembly.
Steel and iron construction with black paint finish delivers long-term structural integrity and corrosion protection suited to the heavy-duty work environments these trucks operate in.
Remanufactured in the United States — ensuring quality oversight, component traceability, and manufacturing accountability throughout the build process.
Backed by a manufacturer warranty — providing professional technicians and fleet operators documented coverage and post-sale confidence on a critical drivetrain component.
