Sway-A-Way VW IRS Axle Set | 33-Tooth Spline | 16 3/4" (2016-7)

Sway-A-Way VW IRS Axle Set | 33-Tooth Spline | 16 3/4" (2016-7)

Sway-A-Way specialized IRS axle set for high-performance Volkswagen Independent Rear Suspension setups. An extended spline design removes the inboard shoulder, allowing the CV joint to float along the shaft.

That float is critical for long-travel off-road buggies or lowered street cars, preventing the CV cage from bottoming out and shattering during extreme suspension articulation.

Vehicle Fitment

• VW Beetle (IRS): 1968–1979
• VW Super Beetle: 1971–1979
• Buggy IRS Builds: All Years

Why Choose Sway-A-Way?

Sway-A-Way manufactures these axles from solid high-strength alloy steel, through-hardens them for the right balance of surface hardness and core flexibility, and centerless grinds them for a consistent diameter and smooth surface.
