Quick Release Steering Systems

Operation Update 25/03/20

SPA is following all government guidelines on the current situation, we are monitoring this situation very closely and will keep you informed on all changes as these happen. We are still fulfilling all orders and doing our best to deliver these on time where possible.


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 splined hub is then hard anodised for both strength and durability.

In addition to the standard 20mm and 23mm internal diameter splined 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 Design steering wheel quick release mechanism conforms 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.
