Axle 31 Spline 32.5in 1.145in OD

The STRANGE OVAL Axle 31 Spline 32.5in 1.145in OD is a precision-engineered axle shaft designed for high-performance rear-end applications in street and competition vehicles. As a mechanic, you know that axle selection is critical to driveline reliability—this 31-spline design distributes torque across more engagement points than conventional 28-spline units, making it the go-to choice for vehicles running aggressive power levels or frequent track duty.

This STRANGE OVAL axle features a 31-spline configuration that provides enhanced load-carrying capacity and reduced stress concentration compared to lower spline counts. The 1.145-inch outer diameter and 32.85-inch length are engineered to fit standard Ford 9-inch and similar third-member housings, with dimensions optimized for vehicles producing 500+ wheel horsepower. The increased spline count means finer tooth geometry, which translates to smoother power delivery and improved durability under repeated hard acceleration or cornering loads.

STRANGE OVAL's reputation for straightness tolerances and material consistency ensures that both axles in a pair maintain balanced characteristics—critical for eliminating power-induced vibration and ensuring predictable handling on the road or strip. This axle is ideal for builders upgrading late-model and classic vehicles to handle supercharged applications, making it a reliable choice for serious automotive enthusiasts.
