Delphi SS21381 ABS Wheel Speed Sensor

The Delphi SS21381 is an ABS wheel speed sensor (also known as an anti-lock brake sensor or vehicle speed sensor) engineered to OE fit, form, and function. Delphi is an original equipment supplier to top global vehicle manufacturers, and this sensor is built to the same rigorous standards used in original factory assemblies.

Key Features:

• OE-quality construction — designed and validated to match original equipment specifications for a precise, reliable fit
• Latest digital signal technology — delivers stable, accurate wheel speed readings in all driving and weather conditions
• Weather-resistant design — features weather pack connectors and plated pins to resist moisture, vibration, and temperature extremes
• OE-matched connector and wire length — allows straightforward installation directly from the box, with no modifications required
• Stainless steel housing — tested for long-term durability and environmental compliance
• Breathable membrane filter — improves air supply for optimal functionality while sealing against water ingress and high temperatures

The SS21381 monitors individual wheel rotation speed and transmits that data to the vehicle's ABS control module, helping prevent wheel lockup during hard braking. Replacing a faulty ABS sensor restores proper function to your anti-lock braking system, traction control, and electronic stability systems — all of which depend on accurate wheel speed data to operate safely.
