SKU 2421
Category: Porsche 930 Performance Axles
Designed for elite high-performance applications, these 21 3/8" Porsche 930 CV axles maximize durability and reduce wear under extreme conditions. The optimized spline diameters enhance face contact, significantly improving drivetrain longevity and reliability during aggressive racing.
Performance & Fitment
Application: Porsche 930 CV Joints (108mm)
Overall Length: 21 3/8"
Spline Count: 28-tooth
Outer Diameter: 1.220" (Spline)
Design Feature: Floating CV Design, engineered to allow the CV joint to travel along the spline. This minimizes lateral stress and prevents cage breakage during the extensive suspension cycling found in long-travel off-road setups.
Geometry: Measuring 21 3/8", this is an "ultra-long" axle specifically designed for wide-track desert racers, dual-sport sand rails, and custom long-travel buggies.
Premium Construction
Material: Solid alloy steel for superior strength and the high torsional resilience required for high-horsepower engines.
Heat Treatment: Through-hardened to enhance durability and "memory," allowing the axle to flex under torque loads and return to its original state without bowing.
Manufacturing: Centerless ground for precise fitment and a perfectly balanced shaft to eliminate drivetrain vibration at high speeds.
Finish: Powder-coated for long-lasting corrosion resistance against moisture, mud, and sand.
⚠️ Critical Fitment Exceptions
Even if you are utilizing a Porsche 930-style drivetrain, ensure your setup does not fall under these exceptions:
❌ Standard VW Splines: This axle features the 28-tooth Porsche spline configuration. It is not compatible with standard 33-spline Volkswagen Type 1 (Bug/Ghia) or Type 2 (Bus) CV joints.
❌ Critical Measurement: Given the 21 3/8" length, you must verify your flange-to-flange distance when the suspension is at its "tightest" point (axle horizontal). If the axle is too long for the chassis width, it will act as a solid punch and destroy the CV cages or the transaxle.
- ❌ Spline Mismatch: This axle is engineered for a 1.220" outer diameter spline. Ensure your CV joint internal "stars" match this specific diameter; a loose fit will lead to premature spline failure, while a tight fit will prevent the "floating" action required for this axle to function.
