Installation Notes and Tips

Verify the vehicle’s brake booster configuration and front application before ordering, since fitment varies by model year and equipment. Confirm connector style, harness routing, and spindle mounting points against the original sensor. For best results, inspect the tone ring, wiring path, and mounting surface during installation on Chevrolet Silverado 1500 and GMC Sierra 1500 applications.
