How does this hub assembly match OEM specifications?

The 513121 hub is manufactured to meet common OEM dimensional and functional expectations—flange diameter, bolt circle and ABS integration mimic factory units. That helps ensure proper wheel mounting, ABS sensor reading and rotational stability after replacement.

• Flange diameter approximately 5.73 inches and flange offset ~1.65 inches
• Bolt circle diameter around 4.53 inches with a 5-lug configuration
• Built-in ABS tone ring for compatible anti-lock braking systems
• Pre-assembled bearing and hub for faster installation

What should I expect during installation and performance?

The unit ships pre-assembled so installation is largely bolt-on for compatible models, which reduces labor versus pressing in a separate bearing. Properly torqued and installed, it provides the intended wheel support and should restore normal play and noise characteristics associated with worn hubs.

• Pre-assembled hub and bearing for quicker replacement
• Designed for front positions on FWD/AWD and rear usage on some AWD setups
• Follow vehicle torque specs and ABS sensor alignment during installation
• Quality-tested construction aiming to meet or exceed OEM performance
