Key Features
- HARDENED ROLLING ELEMENTS: Heat-treated rollers and races deliver improved strength and load resistance, ensuring smooth rotation under radial and axial forces from steering and braking.

- PRECISION-PRESSED BEARING: The bearing is securely factory-pressed into the hub to maintain the correct preload, preventing misalignment and reducing the chance of early bearing failure.

Great customer service. I placed an order for wheels and tires and it was an easy transaction. Make sure you read the expected lead times for delivery however. I misread that part, but the order did arrive in the correct timeframe stated. The Hostile rims and Hercules tires look great. Thank you
