Axle Set - Porsche 930 CV (20 1/4")
Performance & Fitment
Application: Porsche 930 CV Joints (108mm)
Overall Length: 20 1/4"
Spline Count: 28-tooth
Outer Diameter: 1.220" (Spline)
Design Feature: Floating CV Design, engineered to allow the CV joint to travel freely along the spline. This minimizes lateral stress and prevents cage breakage during the massive suspension cycling common in long-travel off-road racing.
Geometry: At 20 1/4", this is an "extra-long" axle typically utilized in wide-track Sand Rails, Class 10 buggies, and custom long-travel desert racing trophy lites.
Material: Solid alloy steel selected for its superior strength-to-weight ratio and high torsional yield point.
Heat Treatment: Through-hardened to increase durability, allowing the shaft to act as a torsion bar under high-torque launches to protect the transaxle gears.
Manufacturing: Centerless ground for precise fitment and a perfectly balanced, concentric shaft to eliminate vibration at high speeds.
Finish: Powder-coated for maximum corrosion resistance against moisture and abrasive track debris.
❌ Standard VW Components: This axle features the 28-tooth Porsche spline configuration. It is not compatible with standard 33-spline Volkswagen Type 1 (Bug) or Type 2 (Bus) CV joints.
❌ Compression Measurement: Because this is an extra-long axle, it is critical to measure your flange-to-flange distance when the suspension is at its narrowest point. If the 20 1/4" length is even slightly too long, the axle will bottom out in the CV cup and cause catastrophic failure to the cage or transaxle housing.
- ❌ Spline Diameter Check: This axle is designed for a 1.220" outer diameter spline. Verify that your aftermarket CV joint "stars" match this diameter; mismatched tolerances can lead to excessive spline wear or assembly interference.
