Carquest Premium hub assemblies have been rigorously quality tested to ensure they meet Original Equipment (O.E.) specifications and provide the same reliability and durability expected from OE parts. All Carquest Premium hub assemblies are coated with an obsidian e-coating that protects the hub from rust and corrosion. Our stringent manufacturing processes and high-quality components allow us to stand behind our Carquest Premium hub assemblies with an industry-leading warranty.

Product Features:

• Engineered for OE fit, form and function
• Fully coated with an obsidian e-coating for enhanced rust and corrosion prevention
• High-quality steel and surface treatments for proper fit and endurance
• Roll-form bearing design applies exact preload for increased durability (where applicable)
• Bearings and seals are engineered to the requirements of each specific vehicle application
• Superior ABS sensors with matching signal and enhanced cord insulation for durability (where applicable)

Fixing a worn wheel bearing usually requires a difficult procedure using a shop press, or purchasing multiple components. This Dorman OE FIX pre-pressed hub includes all critical components already assembled for a fast, simple, safe install.

Application-Specific Engineering Design to ensure the correct fit, function and high performance of the wheel bearing. BCA supplies premium replacement bearings that meet or exceed the OE specifications. Premium Quality Materials are used for forged steel rings, seals, precision cages, rolling elements and premium grease, to ensure that our customers receive a robust, durable product. Seals are customized for each BCA hub based on application-specific materials and design requirements to minimize the chance of contamination and maximize bearing life. Precision Cage on BCA bearings are designed to keep the rolling elements of the bearing spaced correctly. The cages undergo design verification and production validation testing to ensure high quality. Pre-Lubrication of all BCA wheel bearings with premium grease for your convenience. This is a major advantage so you do not have to worry about grease or seal application.

Product Features:

• Wheel bearing kits include required components for complete bearing replacement
• Cups, cones, and rollers are made from casehardened alloy steel of Bearing Quality to provide superior fatigue life and reliability
• Micro-pitting surface finish increases bearing life in applications with insufficient lubrication
• Austenite strengthening process (AS) is a special heat treatment applied to the rolling elements
• For wheel bearings, BCA utilizes Forged Steel in the inner and outer rings that meets our stringent steel quality specifications to optimize bearing life.
• For taper bearings, BCA utilizes Case Carburized Steel for heavy duty shock loads and longer life.
• BCA is recognized as the leading manufacturer of case carburized taper bearings.
