Axle 31 Spline 30.5in 1.130in OD

The Strange Oval Axle 31 Spline 30.5-inch 1.130-inch OD is a precision-engineered axle shaft designed for high-performance differentials and custom drivetrain applications. This gun-drilled steel unit delivers the structural integrity required for aggressive off-road recovery, drag racing, and heavy-duty load scenarios where standard axles fall short. The 31-spline carrier interface paired with a 24-spline drive flange provides the flexibility to match a wide range of rear-end housings and transfer case configurations found in both wheeling rigs and street-driven platforms.

Measuring 30.5 inches in length with a 1.13-inch outer diameter, this axle balances weight savings against torsional strength. The gun-drilled construction reduces unsprung mass while maintaining the critical load-carrying capacity needed under acceleration, cornering, and impact loads. At 7.5 pounds, the shaft integrates into custom builds without adding excessive rotational inertia. The natural steel finish provides a clean baseline for coating applications or can be used as-received for applications where aesthetics are secondary to function. Spline count compatibility across both carrier and flange ends ensures proper engagement and eliminates backlash common in loose-tolerance assemblies.

This axle addresses the needs of builders upgrading factory differentials, fabricating independent rear suspensions, or replacing failed OEM components with aftermarket strength. Whether for sand dune runs, rock crawling, towing heavy trailers, or competitive motorsports, the Axle 31 Spline 30.5-inch serves experienced technicians and fabricators who demand precision fit and verified load ratings. Strange Oval's reputation in the differential and axle market reflects a focus on repeatable quality and correct dimensioning—critical factors when tolerances affect drivability and safety.
