We’re please to announce our first run of bolt-on steering wheel adapter for 2005-2013 Corvettes. As many of you are aware, Chevrolet changed the steering column spline pattern for the 2005 model year rendering all previous steering wheel adapters useless. Most (if not all) adapters currently on the market are generic weld-on adapters. While great for racecars, they make it extremely difficult to reinstall a stock steering wheel if the car is ever put back to stock.
These adapters are CNC machined from 6061-T6 aluminum with a mil-spec black hardcoat anodized finish. The spline pattern is cut with wire EDM to maintain high accuracy and a snug fit.
To ensure an accurate fit, the spline pattern was measured with a very high resolution laser scanner. 850 points were taken, each roughly 0.004" apart to guarantee the pattern could be recreated and we can make a snug-fitting part that won't wear loose over time. This geometry was then replicated in a design that could be reliably machined and measured with modern manufacturing techniques. To verify fitment, we prototyped the design with our in-house 3D printer and bolted everything up: For reference, the steering wheel shown is a Sparco R 345 with a 63mm dish. That puts the wheel in a near-stock position. The bolt pattern is a standard 6 x 70mm M5.
