The Ford 9in Axle 31 Spline W/Bearing 33in from ALLSTAR PERFORMANCE is a heavy-duty rear axle assembly designed for high-performance street, strip, and off-road applications. This axle is particularly suited for custom hot rods, drag racers, and modified trucks that demand reliable power delivery and structural integrity under extreme torque loads.
This axle assembly features a 31-spline design, which provides superior load-carrying capability compared to 28-spline alternatives. The integrated bearing surfaces ensure smooth rotation while maintaining precise axle centering within the housing, which is critical for minimizing runout that can lead to vibration and premature wear. The machined spline profile guarantees tight tolerances, enhancing handling and driveline efficiency.
Ideal for Ford 9-inch differential platforms, this axle assembly balances structural rigidity with a weight of 22.5 pounds, making it a key factor in suspension response and chassis control. Whether upgrading a classic muscle car or building a contemporary performance platform, this axle delivers the strength and precision fitment that distinguishes quality builds from amateur work.
