Features an extended spline design that 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 and shattering during extreme suspension articulation.\u003c\/p\u003e\u003ch3\u003ePerformance \u0026amp; Fitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e High-Performance IRS Rear Axle Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 15 5\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpline:\u003c\/strong\u003e 33-Tooth (1.062\" OD, 2 3\/8\" spline length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVW Type 1 (Beetle\/Bug):\u003c\/strong\u003e High-performance street or off-road IRS builds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVW Type 2 (Bus\/Transporter):\u003c\/strong\u003e Heavy-duty replacement for custom IRS conversions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVW Type 3:\u003c\/strong\u003e Compatible with IRS-equipped Notchback, Squareback, and Fastback models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed to work with standard 33-spline CV joints (typically Type 1 or Type 2 \/ 002 styles depending on the specific hub setup)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePremium Construction\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Manufactured from solid high-strength alloy steel, built to handle the torque loads of high-horsepower air-cooled engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Spline Design:\u003c\/strong\u003e The 2 3\/8\" long spline without a shoulder allows the CV to slide freely, accommodating changes in track width as the suspension moves through its arc, eliminating cage breakage caused by axle bind\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Treatment:\u003c\/strong\u003e Through-hardened to achieve the perfect balance of surface hardness and core flexibility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing:\u003c\/strong\u003e Centerless ground for a perfectly consistent diameter and a smooth surface that resists stress risers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Industrial-grade powder coating for long-term corrosion resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e⚠️ Technical Installation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCV Joint Float:\u003c\/strong\u003e Ensure your CV boots are high-quality and flexible (such as silicone or heavy-duty rubber).
