AAM’s helical differential case is available for Ram, Silverado and Sierra trucks

American Axle & Manufacturing Inc. (AAM) has announced the availability of its TracRite GT helical gear designed limited slip style differential case (AAM part #40099548) made for the 11.5” rear axle used in ¾- and one-ton 2003-2012 Ram and 2001-2011 Chevy Silverado and GMC Sierra trucks.

AAM says each differential assembly is built to OEM specs because they are the same units made for OEM Articleion use. The TracRite GT torque bias is proportional to the throttle, providing a smooth application of torque to the wheels.

“Since this differential uses helical gears, there are no clutch plates to wear and no friction additives are needed,” says Greg Marsh, AAM engineering manager. “The TracRite GT is compatible with ABS, traction and stability control systems.”

Marsh says the TracRite GT provides maximum torque bias without causing a shudder in the vehicle and maintains its torque bias throughout the life of the vehicle.

An AAM rebate promotion for its 8.6-inch gear sets for axle ratios of 3.73, 3.42 or 4.10 began Nov. 1, 2014, and ends March 31, 2015. Qualifying purchases made during that time period are eligible for a $20 Visa card. The AAM 8.6-inch gear sets are designed for a variety of GM vehicles with a 10 bolt rear axle.
