The Delphi Mercedes-Benz ABS Wheel Speed Sensor - SS20645 is a high-quality sensor designed specifically for use in Mercedes-Benz vehicles. It is responsible for detecting the speed of each wheel and relaying this information to the vehicle's anti-lock braking system (ABS). This allows the ABS to accurately control the braking force on each wheel, providing improved stability and control while driving. The sensor is made with durable materials and is precision-engineered to ensure reliable performance and long-lasting use. It is a direct replacement for the original equipment sensor and is compatible with a wide range of Mercedes-Benz models.
