Splined Alum. Steering Hub

The Longacre Splined Aluminum Steering Hub (Part No. 52-56605) is a precision quick-release steering wheel hub designed for high-performance road racing, autocross, and dedicated track vehicles. This aluminum hub features a 360-degree quick-release mechanism that allows drivers to rapidly detach the steering wheel for tight paddock maneuvering, quick vehicle access, or emergency egress—critical functionality in competition environments where pit-to-grid transitions demand speed and efficiency.

Built from lightweight aluminum, the hub reduces unsprung weight at the steering column while maintaining the rigidity required for responsive steering feedback during hard cornering and high-speed maneuvers. The hub accommodates both 5/8-inch and 3/4-inch shaft diameters, making it compatible with most aftermarket quick-release steering columns and quick-change steering wheel adapters commonly found on race cars, circuit vehicles, and purpose-built track machines. The natural aluminum finish resists corrosion under typical garage and paddock conditions while keeping overall assembly weight to just 1.25 pounds. The 360-degree release design means the wheel can be gripped and released from any angle—no fumbling with multi-step procedures during time-critical situations.

This hub is the standard choice for drivers running quick-detach steering systems on competition vehicles, club-level racers transitioning to track duty, and owners of dedicated autocross platforms who prioritize ease of wheel removal. The splined connection provides positive engagement and eliminates play, ensuring the steering wheel remains centered and responsive through multiple attach-detach cycles. Each hub ships as a single unit and integrates with most name-brand quick-release steering wheel components already in the aftermarket racing ecosystem.
