The SPA Technique QR-1 Formula steering wheel quick release boss is designed to fit single seater (formula cars) with a 3 bolt fitment steering wheel. They are suitable for Motorsport use and require welding of the supplied spigot to the steering column.
Available Spigot size: 20mm Hub with 5/8" diameter spigot
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.
*Other Hub/Spigot diameters available on request
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.
