Adapter Plate

The GRANT adapter plate is a universal steering wheel adapter engineered to bridge the compatibility gap between modern 6-bolt steering wheel hubs and classic or aftermarket 5-bolt wheels. This aluminum adapter solves a common modification challenge faced by automotive enthusiasts upgrading their steering systems without replacing their existing wheel. Whether you're restoring a vintage vehicle, installing a performance steering wheel, or adapting legacy components to newer platforms, this adapter plate delivers the mechanical solution needed to achieve a secure, factory-quality fit.

Machined from lightweight aluminum and finished in black anodized coating, the GRANT adapter plate provides structural rigidity while resisting corrosion and maintaining aesthetic appeal. The anodized finish protects against oxidation and road salt exposure, critical for longevity in both street and performance applications. The adapter works by converting the bolt pattern geometry, allowing a 5-bolt wheel to mount securely to a 6-bolt hub interface using precision engineering. The compact dimensions—measuring 4.65 x 2.15 x 5.55 inches and weighing only 0.34 lbs—ensure minimal steering wheel offset change while maintaining proper driver ergonomics and airbag clearance in modern vehicles.

This adapter suits mechanics, car builders, and DIY enthusiasts performing steering system upgrades, restorations, or custom modifications across a wide range of vehicle platforms. Installation requires standard socket tools and takes approximately 15–20 minutes once the airbag and steering wheel are safely removed. The universal design accommodates both OEM and aftermarket steering wheels with 5-bolt configurations, making it an essential component for anyone bridging generational or platform-specific steering components. Proper torque specification and washer use are recommended during installation to ensure vibration-free operation and long-term durability.
