This superb-quality quick-release steering wheel hub has virtually no play. This is the design used for many years by F1 and F3 constructors! A special asymmetric spline allows mating in only one orientation so you will never end up with a cock-eyed steering wheel. Releases easily with a spring-loaded sliding sleeve with four locking balls.
The hub and sleeve portion are CNC-machined aluminum, hard anodized for long life. The EN3B (SAE 1020) steel "slug" which gets welded and/or pinned to your steering shaft. The slug is 20mm (0.784") OD with a 6mm bore. If your steering shaft is larger than 7/8", bore a 20mm hole in the steering shaft and insert the slug. If the steering column is also 20mm OD, just add a sleeve over both.
The hub portion attaches to your steering wheel with a 50mm three hole pattern using 10-32 bolts. Most formula car wheels are supplied undrilled and will have to be drilled by the installer. We also offer a Euro QR Hub to 6-Bolt Steering Wheel Adapter (Part No. SP QRA-103, sold separately) to accept OMP, Momo, and Sparco wheels with the standard 6x70mm hole pattern.
This hub also features an integrated 14 pin Lemo connector set. The electrical connections are automatically engaged or disengaged when the steering wheel is installed or removed. This hub makes it easy to add a variety of functions to your steering wheel without having to fumble with a separate connector. Note that you will need to bore a hole in your steering shaft for the wires to exit.
20mm splines. FIA approved.
Note: This item is not compatible with the SPA brand hub.
