UcarSoon steering wheel hub adapter 5- & 6-hole Black — billet aluminum for Chevy/GMC 1969–1994 (366 counter-spline)

This UcarSoon black billet aluminum hub adapter converts 366 counter-splined steering columns to accept aftermarket 5- or 6-hole steering wheels for Chevy and GMC trucks from 1969–1994.

If you're swapping an aftermarket steering wheel into a classic General Motors truck, this hub adapter provides a robust, black powder‑coated aluminum interface designed for many 366 counter‑splined columns (including popular Flaming River and Ididit replacements). It comes as a complete kit with fasteners and installation hardware to speed up fitment, but please verify spline length and column type before ordering.

How does this adapter fit my Chevy or GMC steering column?

The adapter is made for columns using a 366 counter spline profile and offers a 5‑inch depth from spline end to adapter top, so proper spline engagement is essential. It supports both 5‑bolt and 6‑bolt aftermarket wheel patterns common in replacement wheels.

• Compatible with many Flaming River and Ididit style columns.
• 5-inch maximum engagement length—measure your spline before purchase.
• Accepts either 5‑hole or 6‑hole steering wheels.
• Not intended for expansion-style column connections.

What materials and finishes are used, and why does that matter?

UcarSoon machines the hub from solid billet aluminum and applies a black powder coat for corrosion resistance and a uniform appearance. The construction balances strength and weight, giving a durable mounting surface for steering wheels without adding unnecessary bulk.

• Billet aluminum body for rigidity and long service life.
• Black powder coat finish for wear and corrosion resistance.
• Precision machining for accurate bolt alignment and fit.

What comes in the package and what tools will I need?

The kit is supplied with the adapter and the commonly required fasteners and small tools so you have the basic parts needed for assembly. Note that the kit does not include step‑by‑step instructions, so basic mechanical experience and standard shop tools are recommended.

• Includes the adapter, six small and six large hex bolts, and an Allen wrench.
• Also includes a retaining ring, bell-shaped steel wire, and a black plastic sleeve.
• Installation instructions are not included—socket set and torque knowledge required.

Will this adapter work with my aftermarket steering wheel and accessories?

Most aftermarket wheels that use standard 5‑ or 6‑bolt patterns will mount to this adapter, but confirm bolt pattern and wheel hub center clearance. If your wheel includes horn wiring or quick‑release components, check clearance for the retaining ring and sleeve provided.

• Works with common 5‑ and 6‑hole wheel bolt patterns.
• Confirm wheel center bore and bolt spacing before installing.
• Accessory fit (horn, spacer, quick release) depends on wheel design and clearance.

Who is this for: This UcarSoon hub adapter is aimed at classic truck owners, restorers, and custom builders upgrading to an aftermarket steering wheel on 1969–1994 Chevy and GMC trucks or similar GM models. It's ideal for mechanically skilled DIYers and professional installers who can confirm spline length and column compatibility and who want a durable, black-finished billet solution.
