American Axle & Manufacturing Inc. (AAM), 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-inch 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-inch limited slip differential, AAM says it used the same TracRite GT technology it designed into the 11.5-inch 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,” says 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 offers a comprehensive line of aftermarket axle and driveshaft components that were originally built for OE vehicle manufacturers.

AAM manufactures, engineers, designs and validates driveline and drivetrain systems and related components and modules, chassis systems and metal-formed products for light trucks, sport utility vehicles, passenger cars and crossover vehicles and commercial vehicles. In addition to locations in the United States (Indiana, Michigan, Ohio, and Pennsylvania), AAM also has offices or facilities in Brazil, China, Germany, India, Japan, Luxembourg, Mexico, Poland, Scotland, South Korea, Sweden and Thailand.
