Quick Navigate to a Product Page
Well built — and proven at every stage.
Engineered around the application and verified through the program, from raw material to final inspection.
1. Knuckle + hub, integrated
The knuckle and hub come together as one factory-validated assembly — geometry and fit set before the part reaches the bay.
2. Reduced install time
Replace one preassembled unit instead of pressing the bearing and hub into the knuckle and sourcing multiple individual components.
3. Validated fit & geometry
Components matched and checked as a unit for accurate, repeatable installation.
4. ABS integration
ABS encoder/tone-ring and sensor configuration matched to the application, where equipped.
Checked and tested at every stage
Each assembly is engineered around its application and verified through the program, from raw material to final inspection.
