Wheel Hub Assembly Unit Bearing 1603211

Product Overview

The 1603211 wheel hub bearing unit assembly is an integrated solution designed specifically for precise replacement of original components. This product is strictly manufactured according to the original factory specifications, integrating the wheel hub, high-precision bearings, and ABS induction ring into a closed unit, aiming to fully restore the vehicle's driving stability, braking safety, and steering smoothness, and is suitable for multiple General Motors platform models.

[Core Advantages]

Strict process guarantee: Made of forged alloy steel material, it undergoes heat treatment and precision grinding to ensure smooth bearing raceway and strict tolerance control, significantly reducing friction loss and extending service life.

Integrated sealing design: Equipped with a multi lip oil seal structure, it effectively blocks the invasion of sediment, water vapor, and corrosive substances on the road surface, maintaining the long-term effectiveness of internal lubricating grease and avoiding early failure.

Accurate signal transmission: Equipped with a built-in magnetic coded ABS sensor ring, seamlessly compatible with the original anti lock braking system, ensuring accurate wheel speed data collection and guaranteeing the normal operation of electronic stability systems (such as ABS/ESC).

Vibration and noise control: Optimize internal structure and preload design to reduce abnormal vibration and noise during high-speed driving, and improve driving comfort.

Ready to use design: The assembly style structure eliminates the adjustment steps required for traditional press in bearings, supports direct installation, and significantly saves maintenance time and tool costs.

[Adaptation Information]

Main compatible brands: Chevrolet, Buick, GMC and other models under the General Motors Group

Adaptation reminder: Please prioritize checking compatibility based on the vehicle VIN code or specific year and engine model to avoid installation differences caused by vehicle model changes.
