Specs At A Glance

Good To Know

Q: What are the signs of a bad front axle actuator? A: The most common sign is a transfer case that shifts into 4WD while the front wheels never pull, and some trucks store a service 4WD message. A failed actuator can also cause grinding or no engagement at all.

Q: Is this an original GM part? A: No, this is an aftermarket replacement actuator built to fit Chevy Silverado and Avalanche K1500 and K2500 trucks. It is not manufactured by or affiliated with General Motors.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
