American Axle & Manufacturing 40030759 Rear ABS Exciter Tone Ring for GM 8.6" 10-Bolt Axle

The American Axle & Manufacturing 40030759 is a genuine OE rear axle ABS exciter tone ring (reluctor ring) designed for 2007 and newer GM 1/2 ton trucks and SUVs equipped with rear ABS systems. This precision-engineered component is essential for proper anti-lock brake system operation, working with the wheel speed sensor to monitor wheel rotation and prevent wheel lockup during braking.

Key Features:

• Genuine AAM OE replacement part ensures exact fit and reliable performance
• Features 32 teeth for accurate wheel speed detection (not compatible with earlier 55-tooth models)
• Fits GM 8.6" (8.625") 10-bolt rear axles found in 1/2 ton applications
• Part number is molded into the rubber on the inside of the tone ring for easy identification
• Mounts directly onto the rear axle shaft (one required per side)
• Manufactured to OEM specifications for proper ABS system function

This tone ring is compatible with popular GM vehicles including Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and similar 1/2 ton platforms from 2007 and newer with the 8.6" rear differential. The ring provides the magnetic reluctance pattern that allows the ABS wheel speed sensor to accurately monitor wheel rotation, enabling the anti-lock braking system to function effectively and enhance vehicle safety.
