Axle 31 Spline 29.50in 1.100in OD

The Axle 31 Spline 29.50in 1.100in OD by Strange Engineering is a precision-engineered differential axle shaft designed for high-performance automotive and tactical vehicle applications. Built to OEM specifications, this 31-spline axle delivers the durability and load-carrying capacity required by military personnel, law enforcement fleets, and serious off-road operators who demand reliability under extreme conditions.

The 29.50-inch length and 1.100-inch outer diameter make this a direct fit for vehicles requiring exact dimensional matching in drivetrain assemblies. Strange Engineering's manufacturing process ensures tight tolerances and superior material composition, critical factors in axle longevity under heavy load or high-torque scenarios. The 31-spline design provides maximum engagement surface area, distributing rotational forces evenly across the differential side gears to reduce stress concentrations and prevent premature wear.

At 6.9 pounds, this axle offers an optimal weight-to-strength ratio, maintaining structural integrity without unnecessary mass—a consideration in mobile tactical platforms where every pound affects fuel efficiency and handling dynamics. The precision-ground spline geometry ensures smooth engagement and minimizes backlash, essential for vehicles operating in demanding terrain or high-speed tactical maneuvers. This axle is ideal for fleet maintenance personnel, vehicle restoration specialists, and operators maintaining high-duty-cycle tactical or emergency service vehicles.
