Delphi SS21390 ABS Wheel Speed Sensor

The Delphi SS21390 is an OE-quality ABS wheel speed sensor engineered to deliver precise wheel speed data to your vehicle's anti-lock braking system (ABS) and electronic stability control. As a trusted original equipment supplier to major automakers, Delphi manufactures this sensor to meet or exceed original factory specifications for a reliable, direct-fit replacement.

Key Features:

• OE-matched design helps prevent mechanical damage to the sensor ring, contamination from soiling, and issues caused by increased wheel bearing free play
• Built to maintain optimal performance across a wide temperature range for robust, long-lasting protection
• Magneto-resistive or Hall Effect sensing technology delivers a clean digital signal output for maximum accuracy, especially at low speeds
• Weather-pack connectors and plated pins provide superior signal stability and corrosion resistance in all conditions
• Tested and calibrated to OE standards to ensure accurate readings and reduce the likelihood of comebacks
• Direct plug-and-play fitment — no modifications required

Delphi's ABS sensors are a safety-critical component, monitoring wheel speed and rotation to prevent brake lock-up during hard stops. Choosing an OE-quality wheel speed sensor like the SS21390 ensures the full effectiveness of your vehicle's ABS, traction control, and stability systems is maintained.
