AAMAmerican Axle & Manufacturing (AAM), a leading manufacturer of axle components, driveshaft components and repair kits for OE vehicles, has announced the availability of a helical gear limited slip differential case (AAM part #40135974) for 1999-2015 GM pickup trucks with an 8.6” rear axle.

AAM’s limited slip differential case is not a locking differential case, but does provide many traction enhancing capabilities under most driving conditions, especially for vehicles equipped with traction control systems. To manufacture the 8.6” limited slip differential, AAM utilized the same TracRite GT technology it designed into the 11.5” limited slip differential for 2001-2011 GM pickup trucks.

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

Marsh said the TracRite GT provides maximum torque bias, without causing a shutter throughout the life of the vehicle. The TracRite GT torque bias is proportional to the throttle, providing a smooth application of torque to the wheels.

AAM differential cases are machined and assembled to the high quality standards and tolerances that original manufacturers require. They are designed and tested for each specific vehicle application. Low pinion flange run out, a key specification, is assured for maximum quietness.

AAM parts are the same OEM production parts many shops have come to demand when installing replacement parts. AAM parts fit right, install right and perform right the first time.
