Detailed Product Description

The Timken HA590027 is a wheel bearing and hub assembly designed to meet the exact specifications required by Nissan 350Z and INFINITI G35 models. This assembly features a flange with four bolt holes and five wheel studs, providing a secure and stable connection to the vehicle’s suspension and wheel. The precise wheel pilot diameter of 2.598 inches (66.00 mm) and brake pilot diameter of 2.677 inches (68.00 mm) ensure proper alignment with the brake rotor and wheel, reducing vibration and improving handling. The hub pilot diameter of 3.307 inches (84.00 mm) supports the hub’s fitment to the axle flange, while the flange offset of 1.604 inches (40.75 mm) maintains correct wheel positioning relative to the suspension geometry. This non-driven hub assembly is engineered for vehicles where the hub does not transmit power but supports wheel rotation and braking components.
