19 1/4 Axles 33 Spline Pair Fits VW Type 1 & 2 CV Joints

OVERVIEW

When you are pushing the limits of your off-road machine, your drivetrain is only as strong as its weakest link. These EMPI 19-1/4 inch Chromoly axles are engineered specifically for long-travel suspension setups, providing the necessary length and durability for high-performance applications. Manufactured from high-strength 4340 Chromoly steel and finished with a protective zinc plating, these axles are designed to withstand the brutal torque and extreme angles encountered in desert racing, dune jumping, and rugged trail riding. By utilizing a 33-spline configuration, these axles offer a significant upgrade in surface area contact over standard stock components, ensuring that your power is delivered to the ground without the fear of snapping a shaft under heavy load.

These axles are the gold standard for builders running a Volkswagen Type 2 (002 or 091) transmission paired with 3x3 extended trailing arms. The 19-1/4 inch length is the industry-standard dimension for this specific suspension geometry, allowing for maximum articulation while maintaining proper CV joint engagement. Whether you are building a dedicated sand rail, a Baja Bug, or a heavy-duty Manx-style buggy, these axles provide the versatility to work with either Type 1 (94mm) or Type 2 (100mm) CV joints. Sold as a pair, they represent a critical component in achieving a reliable, long-travel IRS (Independent Rear Suspension) system that won''t leave you stranded in the middle of the wash.

FITMENT

These axles are designed for custom high-performance applications and typically fit the following configurations:

• Volkswagen Beetle (Type 1): Equipped with aftermarket 3x3 trailing arms and IRS suspension.
• Volkswagen Karmann Ghia: Equipped with aftermarket 3x3 trailing arms and IRS suspension.
• Volkswagen Thing (Type 181): Equipped with aftermarket 3x3 trailing arms.
• Volkswagen Bus (Type 2): Used in custom mid-engine or rear-engine sand rail applications utilizing Type 2 transaxles.
• Sand Rails & Dune Buggies: Specifically designed for chassis using 3-inch wider and 3-inch longer (3x3) rear trailing arms.
• CV Joint Compatibility: Fits standard 33-spline Type 1 (94mm) and Type 2 (100mm) CV joints.

PRO TIPS

1. Verify Axle Float and Suspension Travel

Before completing your installation, it is absolutely critical to check for "axle float" throughout the entire range of suspension travel. With the shocks removed, move the trailing arm from the highest point (full compression) to the lowest point (full droop). At any point in this arc, the axle should have a small amount of lateral movement (roughly 1/8 to 1/4 inch). If the axle "bottoms out" against the CV joint stars at either extreme, you risk shattering the CV cage or damaging the transmission drive flanges. Always adjust your limit straps and bump stops to prevent the axle from becoming a structural member of the suspension.

2. Proper CV Joint Lubrication and Maintenance

High-angle off-road use generates significant heat within the CV joints. Always use a high-quality, high-moly content CV grease specifically formulated for off-road racing. When installing these 33-spline axles, ensure the splines are clean and free of burrs before sliding the CV joint on. We recommend using a heavy-duty CV boot made of Hytrel or high-grade silicone to withstand the increased angles associated with 3x3 arms, as standard rubber boots will often tear or melt under the stress of long-travel articulation.

3. Match Your Splines and Clips

While these axles are designed for 33-spline Type 1 and Type 2 CV joints, always double-check your joint fitment before assembly. Ensure that the snap rings are fully seated in the axle grooves. A snap ring that isn''t properly seated can allow the CV joint to "walk" on the axle, leading to a catastrophic failure of the splines or the joint itself. If you are upgrading from a stock 28-spline setup, remember that you must change your CV joints and potentially your drive flanges to accommodate the larger, stronger 33-spline architecture of these Chromoly shafts.
