Proline has pioneered every major advance in wheel end technology since the invention of the automobile, and our commitment to innovation continues today.
With expertise in not only bearings but seals, lubrication, and mechatronics, Proline is able to look at wheel end technology from a systems viewpoint. The result is improved functionality, reliability, efficiency, and safety. As a supplier of original equipment hub units to most of the worlds leading automakers, Proline knows better than anyone what goes into making a premium quality hub unit.
From the composition of the steel to the quality of the bearing and seals, every aspect of a hub unit is critical to long service life. Imprecise tolerances and poor surface finishing can cause noise and vibration, and low quality reproduction sensors can compromise ABS function. The truth is, they can't.
The results were clear: these hubs were NOT OE quality hubs. They were value grade hubs, which are no real value. Not only do they fail quickly, they can result in excessive NVH (noise, vibration and harshness), braking and handling problems, and expose drivers to potential safety risks.
All replacement hub units are not created equal.
