IRS AXLES

IRS axles rely on constant velocity (CV) joints to transfer power while allowing the suspension to move independently. We stock everything from standard-length replacement shafts to heavy-duty chromoly axles engineered to withstand the steep angles and high torque loads of off-road racing. Our inventory covers various lengths and spline counts to ensure a perfect fit for Type 1, Type 2, and custom rail applications.

Our IRS Axle Selection Features:

• Stock & Custom Lengths: Available in standard dimensions for Beetle and Bus, as well as extended lengths for wide-track off-road suspension kits.

• Heavy-Duty Chromoly Options: Forged from high-grade 4340 chromoly to prevent twisting and snapping during hard launches or rough terrain.

• Precision Spline Machining: Ensures a rock-solid interface with your CV joints and drive flanges, reducing slop and drivetrain vibration.

• Versatile Compatibility: Perfect for standard VW CV joints as well as high-articulation Porsche 930 CV conversions.

• Corrosion-Resistant Finishes: Many of our axles feature protective coatings to stand up to the mud, sand, and salt encountered on and off the road.
