Review on High-Quality ABS Wheel Speed Sensor Compatible with Chevy Silverado, Tahoe, GMC Sierra, and Cadillac Escalade by Carlos Macy

The difference in quality between this unit and the original equipment is obvious. However, it works. We'll just see how long that lasts. The OEM sensor has 2 fairly thick O-rings. It only has a very thin O-ring. It only comes out 6 1/2 while the OEM had 7. I'm not sure what that means exactly. This item costs about 5 times LESS than the original part. So obviously there will be a quality exchange.
