Built to match OEM electrical and mechanical connections, these sensors transmit wheel-rotation information to your vehicle's anti-lock braking system and traction control, helping the vehicle interpret wheel speed for stability control functions. Fitment details and reference numbers are included so you can confirm compatibility before ordering.
