MPI Lightweight Aluminum Steering Wheel Quick Release Hub (5 & 6 Bolt Pattern)

Introducing the QR-R1-56 meticulously crafted to cater to the diverse needs of both GT and drag racing enthusiasts. This innovative quick release boasts dual compatibility with the universally recognized 6x70mm bolt pattern, ideal for GT and road cars worldwide, alongside the specialized 5-bolt Grant pattern, favored in drag racing circles.

What sets the QR-R1-56 apart is its precision engineering, offering virtually zero free play with tolerances finer than 0.001 inches. This ensures a snug fit and consistent performance, crucial for high-speed maneuvers. The design is exceptionally lightweight, enhancing agility without compromising durability.

Unique to the QR-R1-56 is its unidirectional installation feature. Once mounted, the steering wheel retains its exact position, thanks to intelligently designed splines and body contours. This not only simplifies installation but also guarantees reliability during intense racing conditions.

Additionally, the QR-R1-56 is offered with a bolt-on or weld-on spline, providing flexibility in installation methods to suit different preferences and racing requirements
