Steering Wheel Quick Release

The involuted spline design of the SPA steering wheel quick release mechanism incorporates a master spline that allows both perfect orientation and alignment. The steering wheel boss is manufactured from aircraft specification material and the inner splinned hub is then hard anodised for both strength and durability.

In addition to the standard 20mm and 23mm internal diameter splinned mechanisms we have now introduced a range of Electric quick release that incorporate Lemo 8 pin connectors in both the hub and shaft, these mechanisms are available in 20mm diameter spline format. The electric quick release comes pre-wired with 1 metre on the shaft and 1/2 metre on the hub enabling the customer to mount all the necessary controls and switches on the steering wheel without the usual unsightly wiring wrapped around the steering column.

SPA Steering Wheel Quick Releases are SFI Spec 42.1 Approved

SPA Steering Wheel Quick Releases conform to the latest FIA technical specification as defined in Appendix J Article 255 dated 01-01-03 5.7 3.7 Steering Wheel.

The quick release mechanism must consist of a flange concentric to the steering wheel axis coloured YELLOW through anodisation or any other durable yellow coating and installed on the steering column behind the steering wheel.

The release must be operated by pulling the flange along the steering wheel axis.

Special Applications:

SPA Design has the capability to manufacture a wide variety of Steering Wheel Quick Release Systems and this service is available to all constructors. Buy online today or contact for more information.
