OEM 80 Series axles use a strong 30-spline differential side, but neck down to a coarse 24-spline CV, creating a weak link that often fails under heavy loads, big tires, or locked up trail use.\u003c\/p\u003e\n\u003cp\u003eRCV eliminates this bottleneck by upgrading the CV joint to a 4340 chromoly 30-spline race, eliminating the neck down section entirely and dramatically increasing torsional strength.
