Sway-A-Way VW IRS Axle Set | VW Beetle, Super Beetle & Buggy | 33-Spline (SAW-2021-1)

Sway-A-Way VW IRS Axle Set — 33-Spline (SAW-2021-1)

The Sway-A-Way VW IRS Axle Set is a specialized axle solution for high-performance Volkswagen Independent Rear Suspension (IRS) setups. Its extended spline design removes the inboard shoulder, allowing the CV joint to float along the shaft — critical for long-travel off-road buggies or lowered street cars to prevent the CV cage from bottoming out during extreme suspension articulation.
