Apec ABS Ring (ABR121)

This Apec ABS Ring (ABR121) is supplied in OE matching quality and has been thoroughly tested for accuracy and endurance to maintain the superior quality of Apec products.

The gear-like shaped ABS Ring (also known as the rotor or sensor ring) acts as a counterpiece to the ABS speed sensor for recording the speed or the speed change of the wheel on which it is installed. The constant alternation of tooth and tooth space during wheel rotation causes a change to the magnetic field in the ABS sensor, resulting in the induction of sinusoidal AC voltages. Their frequency depends on the wheel speed and is evaluated by the ABS control unit.

High-quality, reliable ABS rings are important because a damaged ABS ring can have a significant impact on the performance of the ABS, reducing the control of your vehicle and extending braking distance, which reduces safety. Apec ABS Rings are designed as direct replacements for OE counterparts and contain an anti-corrosion coating that provides great resistance against even the most extreme environmental hazards and conditions.

A market-leading specialist in supplying reliable braking components, Apec is a brand you can trust with over 50 years of experience in the automotive aftermarket.
