McHenry — April 1st, 2008 The only hub assemblies in the world good enough to carry the Raybestos® Brand Professional Grade™ name are available in three generations to cover almost all applications. These hub units are manufactured by OE suppliers and feature more coverage than short-line economy offerings. The expanded line features new packaging, a torque spec guide, installation instructions and warning tags.

Raybestos® hub assemblies offer more SKUs for greater than 95% coverage. Starting with OE specs, these parts are engineered with improvements and solutions to problems discovered after the OE parts have been subjected to the grueling realities of real life driving. The manufacturing process includes continuous testing for endurance, temperature control, hydraulic and salt resistance, metallurgical integrity and vibration.
As with all automotive technology, hubs have evolved as the demands for lighter, smaller, simpler-to-install and durability-maximized products have increased on the part of OE Manufacturers. All three generations of Raybestos® hubs take advantage of newly available computerized machining techniques to produce a simplified, much more precise hub that consists of only three major parts with much tighter tolerances. They are maintenance-free, self-contained and preloaded – and require no adjustment.

Less sophisticated machining procedures used by economy manufacturers not wanting to invest in the latest technology requires the use of more pieces. That’s why Raybestos® hubs feature on average 40% fewer parts. These parts are machined more precisely for longer hub life and less problems down the road.
