Assembled disconnect control units for GM SUVs are available from AAM

American Axle & Manufacturing Inc. (AAM) has released an OE disconnect control unit for the 7.25-inch front axle 2002-2009 Chevy Trailblazer and GMC Envoy SUVs.

The unit is available in two versions:

* one with the actuator (AAM part #74080002A); and

* one without (AAM part #74080002B).

AAM also packages the disconnect unit in a shifter kit (AAM part #7480002) that includes the actuator, so all components are available for ease of installation by technicians. The components in these kits directly replace the original unit. 

In addition to the actuator, the kit contains the return spring, shifter fork, tube bolt, thrust washer, shifter sleeve, I/O shaft assembly, shifter housing, differential carrier thrust washer, differential shifter seal, carrier connector, differential shifter spring and differential thrust washer.

AAM says all of these components have been designed, manufactured and validated to the vehicle manufacturer's specifications and produced from the original design to meet the OE specifications.
