UcarSoon Steering Wheel Hub Adapter 5 & 6-Hole, Black Billet Aluminum, 5in Depth for 366 Counter-Splined Columns

UcarSoon's black billet aluminum hub adapter converts 366 counter-splined aftermarket steering columns into a secure 5- and 6-hole mounting interface for classic GM and compatible vehicles.

This precision-machined steering wheel adapter is made from high-quality billet aluminum with a durable black powder coat finish. It is engineered to mate with most after-market 366 counter-splined columns (including popular Flaming River and Ididit-style units) and provides a robust connection between the column spline and an aftermarket steering wheel. The kit ships with the adapter plus hardware so you can complete the installation if you already have the correct column and wheel. Confirm spline length and fitment before ordering because this adapter measures 5 inches from spline end to adapter top and is not intended to expand to other spline types.

Will this hub adapter fit my 1969–1994 Chevy or GMC truck?

The adapter is designed to work with most 366 counter-splined aftermarket steering columns commonly used in classic Chevy and GMC restorations from 1969–1994. It suits many American models and GM platforms when the column uses the same spline specification. Always measure the spline length and compare your column to the adapter's 5-inch depth specification to ensure compatibility.

• Works with 366 counter splined columns (Flaming River, Ididit-style)
• Not compatible with factory-expansion-style splines
• Adapter depth: 5 inches from spline end to adapter top
• Intended for aftermarket columns, not all factory originals

What hardware and parts are included in the package?

The kit arrives with everything needed to attach the adapter to a steering wheel and column, excluding step-by-step installation instructions. Included fasteners and accessories let you secure the adapter to a variety of wheel patterns and ensure the retaining components are in place during assembly.

How durable and reliable is the finish and material?

Machined from billet aluminum for strength and precision, the adapter is finished with a black powder coat to resist wear and corrosion during everyday use and restoration projects. The construction balances lightweight performance with long-term durability so it holds up under steering loads without adding unnecessary weight.

• Billet aluminum body for consistent fit and rigidity
• Black powder coat resists abrasion and environmental wear
• Designed for repeated assembly/disassembly during restoration

Who is this for: This adapter is aimed at classic GM owners, hot-rod builders, and restoration shops converting to aftermarket 366 counter-splined steering columns. If you have an aftermarket column of the correct spline profile and you want a sturdy, well-finished hub for a 5- or 6-hole steering wheel on Chevy, GMC, Pontiac, Buick, Chrysler, Dodge, or similar American models, this adapter is a practical choice. Do a quick measurement of your column spline length and confirm your wheel bolt pattern before purchasing to ensure a correct fit.
