The best 3-bolt steering wheel adapter depends on your vehicle, steering column, and wheel bolt pattern. The Speedway Motors kit is best for specified 1969–94 GM, Ididit, and Flaming River columns; the United Pacific kit covers a range of 1949–80 GM vehicles. RULLINE and BDZMC are conversion spacers for attaching a 6-hole wheel to a 3-hole hub, while the Grant kit is for installing select Grant steering wheels.

Grant 3163 Installation Kit
Best for: Drivers installing a Grant Classic Series, Challenger Series, or Signature Series steering wheel. This vehicle-specific installation kit is selected for buyers who need a kit made for those Grant wheel lines rather than a general-purpose 6-to-3-hole spacer.
Features include matte black trim pieces and complete step-by-step instructions. Check that the kit matches both the vehicle application and the specific Grant wheel before ordering.
Limitation: The listed application is for select Grant series; the product details do not establish compatibility with other steering wheels.
Speedway Motors GM 3-Bolt Column Kit
Best for: Owners of specified 1969–94 GM, Ididit, or Flaming River steering columns who want to install an aftermarket 3-bolt wheel. It is the most directly specified option here for that column and vehicle range.
The kit includes a black metal cover, horn button spring, spacer ring, plunger spring, lead wire, and three mounting bolts. These components make it a more complete choice for buyers seeking mounting and horn-related parts together.
Limitation: The stated compatibility is limited to the listed GM years and column types. Verify the exact column before purchase rather than assuming it fits all GM vehicles.
RULLINE 6-To-3-Hole Hub Spacer
Best for: Buyers who already have a 3-hole hub adapter and need to attach a 6-hole steering wheel. Its stated purpose is pattern conversion, so it is better suited to resolving a bolt-pattern mismatch than replacing a vehicle-specific column adapter.
The spacer is listed as 0.5 inches thick, with a 0.55-inch inside diameter and 3.51-inch outside diameter. The package includes hex bolts and 10-32 x 1/2-inch flat Allen head screws. Compare these measurements and the wheel’s hole pattern with your existing hub before choosing it.
Limitation: This is a 6-hole-to-3-hole spacer, not a complete steering-column installation kit.
BDZMC Aluminum 6-To-3 Spacer
Best for: Buyers converting a 6-hole wheel to a 3-hole hub who want a spacer with stated material and fit measurements. The listing describes an aluminum construction and a black protective surface layer.
Its listed dimensions are a 0.55-inch inside diameter and 3.51-inch outside diameter. The application information specifies a 35 mm (1.375-inch) distance from the hub center to the six holes, or a 70 mm (2.75-inch) hub diameter measurement. Check those figures against your components before purchase.
Limitation: The stated application depends on matching measurements; the listing does not describe it as a complete vehicle-specific adapter kit.
United Pacific Early GM Hub Adapter
Best for: Owners of compatible 1949–80 GM vehicles installing a 3-bolt mount steering wheel. The listed fit range and compatibility with United Pacific and other manufacturers’ 3-bolt wheels make it a useful option for older GM applications.
The kit includes a splined hub, horn contact plate, and hardware. It is sold as one hub adapter kit, making the quantity clear for buyers comparing packages.
Limitation: The horn button cap is not included. Confirm that the vehicle and wheel match the stated application before ordering.
Buying Guide: How To Choose A 3-Bolt Steering Wheel Adapter
Does the adapter fit your vehicle and steering column?
Start with the vehicle year, make, and steering column type. A vehicle-specific kit such as the Speedway Motors option lists a defined GM year range and column brands. The United Pacific kit lists a separate early GM range. Do not treat those ranges as interchangeable; confirm the application for your exact setup.
Do you need a complete kit or a pattern spacer?
A complete installation kit may include a hub, mounting hardware, trim, or horn components. A 6-to-3-hole spacer addresses a different problem: matching a six-hole wheel to an existing three-hole hub. Choose a spacer only when the hub and wheel patterns correspond to its stated purpose and measurements.
What should you check before ordering?
- Count the mounting holes on the wheel and hub, and identify each bolt pattern.
- Compare stated dimensions with your existing components.
- Check whether the kit includes the horn parts or button you need.
- Confirm whether the listing covers your steering column and vehicle application.
- Review the package contents so you know whether it is one adapter or a broader installation kit.
Frequently Asked Questions
What does a 3-bolt steering wheel adapter do?
It connects a compatible steering wheel to a hub or steering-column setup with a three-bolt mounting pattern. The exact adapter needed depends on the vehicle, column, and wheel.
