ACDelco ABS Wheel Speed Sensor Reluctor Ring

The ACDelco ABS wheel speed sensor reluctor ring (also called a tone ring, exciter ring or ABS encoder ring) is a toothed or magnetically encoded ring. The wheel speed sensor reads it to measure how fast each wheel is turning. The ABS module uses this signal to control anti-lock braking. Traction control and stability control systems use it too.

Key Features:

• Gives the wheel speed sensor a precise, consistent signal for reliable ABS operation
• Replaces a cracked, corroded, damaged or missing reluctor ring, a common cause of ABS warning lights and erratic wheel speed readings
• Built to ACDelco's standards for fit, function and durability
• Supports ABS, traction control and electronic stability systems that rely on accurate wheel speed data

ACDelco is General Motors' original equipment parts brand and has a long history of making replacement parts. Choosing the correct reluctor ring helps restore accurate wheel speed signals and keeps the braking system performing as designed.
