Axle 31 Spline 33.0in 1.115in OD

The Axle 31 Spline 33.0in 1.115in OD from STRANGE OVAL is an essential drivetrain component designed for high-performance automotive applications, particularly in custom drag racing, street machines, and heavy-duty performance vehicles. This precision-engineered axle shaft is built for builders and enthusiasts who demand reliability under extreme torque loads and acceleration stress. Whether you're assembling a competition-grade rear end or upgrading a street rod, this axle delivers the strength and precision required to handle serious power delivery without compromise.

The 31-spline design provides superior load distribution compared to 28-spline alternatives, transferring power more efficiently across a greater contact surface area. The 1.115-inch outer diameter and 33-inch length create a balanced geometry suited for mid-width and full-width rear axle housings, ensuring proper centering and minimal runout during operation. STRANGE OVAL's manufacturing standards guarantee tight tolerances and consistent spline geometry, critical factors that prevent slippage and premature wear even during repeated wide-open-throttle launches and sustained high-RPM operation. At 7.6 pounds, this axle combines structural integrity with manageable weight for better overall vehicle dynamics.

This axle shaft is ideal for mechanics and fabricators building or refreshing independent rear ends for muscle cars, hot rods, and dedicated track vehicles. Proper installation requires press-fitting into compatible hubs and bearing races with precision alignment—any runout exceeding 0.015 inches will cause vibration and uneven loading. Verify hub spline count, bearing bore diameter, and overall axle housing width before ordering to ensure seamless fitment. The 33-inch length works well with most standard-to-narrow rear axle housings; custom lengths are available through STRANGE OVAL for specialized applications.
