1" Steering Wheel Hub Adapter — 6-Hole to 3-Hole Conversion Spacer — Universal Boss Kit
Got a 6-bolt hub and a 3-bolt steering wheel that won't mate up? The iFJF 1" Steering Wheel Hub Adapter solves the mismatch instantly. Precision CNC-machined from billet aluminum, this 1-inch thick conversion spacer adapts standard 6-hole steering hubs to accept virtually any 3-bolt aftermarket steering wheel — including Grant, Forever Sharp, APC, and most universal 3-bolt patterns. The 1" thickness provides a comfortable reach adjustment while maintaining proper steering column geometry. Complete kit includes the adapter spacer, all Grade 8 mounting hardware, and clear installation instructions. No welding, no drilling, no permanent modifications.
Key Features
-
6-to-3 Hole Conversion: Adapts standard 6-bolt steering hubs (70mm PCD) to 3-bolt steering wheels (common Grant/Forever Sharp/APC bolt pattern). Solves the most common hub-to-wheel mismatch.
-
CNC Billet Aluminum: Precision-machined from solid 6061 aluminum billet — not cast, not stamped. Ensures perfect bolt hole alignment with zero slop or vibration.
-
1" Spacer Thickness: Provides comfortable steering wheel reach adjustment. Brings the wheel 1" closer to the driver — ideal for taller drivers or racing seat installations.
-
Universal Fitment: Compatible with Grant, Forever Sharp, APC, and most other aftermarket 3-bolt steering wheels. Also works with many quick-release hub systems.
-
Complete Kit: Adapter spacer + all Grade 8 mounting hardware included. Bolts and thread-locking washers for both hub-side and wheel-side mounting.
-
Corrosion-Resistant Finish: Anodized surface treatment protects against rust and oxidation for years of reliable service.

Installation Overview
- Remove the existing steering wheel from your hub (if applicable).
- Verify the 6-hole bolt pattern on your hub matches the adapter's mounting holes.
- Attach the adapter to the hub using the included bolts — apply thread locker and torque evenly in a star pattern.
- Mount your 3-bolt steering wheel to the adapter using the wheel-side bolts.
- Test with firm hand pressure in all directions — no play, no clicks, no movement before driving.

Frequently Asked Questions
Q: Will this fit my Grant steering wheel?
A: Yes. The 3-bolt pattern on this adapter matches Grant's standard 3-bolt steering wheel mounting pattern — one of the most common aftermarket configurations.
Q: Does this work with a quick-release hub?
A: Yes, in most configurations. This adapter sits between your 6-bolt hub and your 3-bolt wheel. If you're using a quick-release, the adapter typically mounts between the quick-release and the steering wheel.
Q: Is the 1" spacer thickness noticeable?
A: Yes — 1" of additional reach brings the wheel noticeably closer, which many drivers find more comfortable, especially with racing seats or when the factory wheel is too far away.
Q: Do I need thread locker?
A: We strongly recommend blue (medium-strength) thread locker on all bolts. Steering components are safety-critical — loose bolts are not acceptable. A small tube of Loctite 242 is cheap insurance.
Q: What if my bolt pattern doesn't match?
A: Measure your hub and wheel bolt circles carefully before ordering. Standard 6-bolt is 70mm PCD. Standard 3-bolt is common on aftermarket wheels. Contact support with your measurements if unsure.
