Our Top 8 Most Popular Fiat B-G Boss Kits
Need help narrowing it down? Below are some of the most popular Fiat boss kits our customers are upgrading with — from Abarth classics to everyday Punto and Grande Punto models. Each of these kits provides bolt-on compatibility, offering a great starting point for both first-time modders and seasoned builders alike.
Find the Right Boss Kit for Your Car
A boss kit is an essential part of any aftermarket steering wheel installation, providing a secure and vehicle-specific connection between your car’s steering column and the new steering wheel or quick-release hub. Since every car has a different steering shaft design, a universal steering wheel won’t fit directly without a boss kit acting as the bridge between the two.
No matter what vehicle you drive, using a high-quality boss kit ensures a secure, safe, and professional installation.
