EMPI Banjo Steering Wheel Boss Kit - Polished Billet Aluminum - 40-Spline (1960-1974½)

Bridge the gap between vintage elegance and precision engineering with the EMPI Polished Billet Aluminum Banjo Boss Kit. This adapter is the essential mechanical link required to mount a 3-bolt Banjo-style steering wheel to your classic Volkswagen steering column.

Machined from high-grade billet aluminum and finished to a mirror polish, this boss kit doesn't just provide a secure mounting point—it serves as a seamless extension of your interior's aesthetic. Unlike cast adapters, this billet piece offers superior structural integrity and a crisp, clean look that complements both stock and custom dashboards.

Key Features

• Premium Billet Construction: CNC-machined from solid billet aluminum for maximum strength and a flawless polished finish.

• 40-Spline Precision: Specifically Broached for the 21mm coarse-spline steering shafts found on the most popular air-cooled production years.

• Complete Installation Hardware: Includes the necessary mounting bolts, column nut, and wiring connectors to ensure your horn remains fully functional.

• Seamless Integration: Designed to match the diameter and taper of the factory steering column for a "built-in" appearance.

Vehicle Fitment

This boss kit is designed for the 40-spline / coarse-spline steering shafts.

Tech Tip: 1974 is a transition year. If your steering column has the wiper switch on the stalk (fine-spline), this adapter will not fit. This is for the earlier coarse-spline (21mm) columns.
