Is your truck's ABS light on? A faulty wheel speed sensor could be the culprit. This 2-pack of replacement ABS sensors is compatible with Meritor Wabco systems, specifically replacing part numbers 4410328140 and 4410326180. They're unbranded/generic but made to meet or exceed OEM specifications. Each sensor is black and silver, made from ABS plastic and metal, and has a length of approximately 2.1 meters (about 6.88 feet), which should reach the connector in most truck applications. These sensors monitor wheel rotation speed and send data to the ABS computer – crucial for anti-lock braking system function. Installing new sensors can resolve warning lights, restore ABS functionality, and improve safety. The pack of two is convenient if you're doing both sides or want a spare. Always check compatibility with your specific truck model and year before ordering. A cost-effective solution for truck owners and fleet managers to maintain braking system integrity.
