MOCW Billet Steering Wheel Hub Adapter for GM & Chevy Columns — 5 & 6-Hole, Black Powdercoat

If you’re swapping a steering wheel into a GM vehicle or installing a Flaming River/Ididit column, the right hub adapter keeps the fit secure, the steering column functional, and the look clean. This MOCW adapter is CNC-machined from billet aluminum, finished in black powdercoat, and includes the spacer, bolts, ground wire and grade-5 hardware you need for a tidy install. It supports most common 5- and 6-hole wheel patterns—making it a versatile choice for restorations, hot-rods, and daily drivers alike.

Which vehicles and columns is this adapter compatible with?

This hub is designed for late-model GM splined columns and covers a broad range of Chevrolet cars and trucks. It fits Chevrolet passenger cars from 1969–1994 (with listed exclusions) and Chevy trucks from 1974–1994, and it works with Flaming River and Ididit columns that use the same GM spline size.

• Compatible with most GM columns using 11/16" x 36 spline I.D.
• Works with Flaming River and Ididit columns that use late-model GM splines
• Fits Chevy cars 1969–1994 excluding Corvette, Sprint, Spectrum, and 1986–1988 Nova
• Fits Chevy trucks 1974–1994 and Sprint/El Camino/Caballero 1967–1988

Which steering wheels will bolt to this MOCW adapter?

The adapter accepts most standard 5- and 6-hole aftermarket wheels from major brands. It will not match every pattern—Nardi and Personal 6-hole patterns are explicitly incompatible—so check your wheel’s bolt pattern before ordering.

• Fits Grant, Sparco, Lecarra, GT Performance, APC, Pilot, Superior, and many others
• Accepts both 5-hole and common 6-hole bolt patterns (excluding Nardi/Personal)
• Uses included grade-5 hardware and three hex bolts for secure attachment
• Includes a ground wire for horn continuity when needed

What are the build details and materials?

The MOCW hub is milled from billet aluminum for strength and precision. A black powdercoat finish improves surface durability and resists corrosion, while the included spacer and hardware make for a complete mounting kit out of the box.

• Billet aluminum construction for rigidity and precise fit
• Black powdercoated surface for wear resistance and longevity
• 11/16" x 36 spline I.D. designed for late-model GM splines
• Comes with spacer, three hex bolts, ground wire, and grade-5 hardware

How straightforward is the installation?

Installation is a standard hub swap on compatible columns and generally requires common hand tools. The package contains the main hardware; however final steps depend on your vehicle’s horn wiring and any column modifications.

• Includes all primary mounting hardware; use a torque wrench for safety
• Standard 11/16" x 36 spline fitment means no custom machining for most GM columns
• Ground wire included for horn circuit continuity; verify vehicle wiring before connecting
• May require removal of the factory boss or column trim for access

Who is this for: Car builders, classic Chevy owners, and aftermarket wheel enthusiasts who need a durable, no-nonsense hub adapter for GM-splined columns. If you’re upgrading to a common 5- or 6-hole wheel and you own a compatible Chevrolet or a Flaming River/Ididit column with late-model GM splines, this MOCW billet hub provides a clean, secure mount with included hardware and a corrosion-resistant finish. Confirm your wheel’s bolt pattern and your column’s spline size before purchasing to ensure fitment.
