Wide 5 31 Spline Solid Axle 30.5in Long

The PEM Wide 5 31 Spline Solid Axle is a 30.5-inch axle shaft engineered for high-performance drivetrain applications requiring robust load-carrying capacity and precision spline engagement. This solid axle features a 31-spline carrier configuration paired with a 24-spline drive flange, making it suitable for vehicles undergoing suspension upgrades, off-road modifications, or performance builds where factory axle geometry or strength is insufficient for intended duty.

Manufactured from steel in natural finish, this 10-pound axle shaft provides the structural integrity demanded by lifted trucks, rock crawlers, and vehicles equipped with larger tires or modified gearing. The 31-spline carrier design maximizes contact area with the differential, distributing torque across a broader surface to reduce stress concentrations—critical when upgrading suspension geometry or increasing wheel diameter. The 24-spline drive flange interfaces with compatible wheel hubs, offering a standardized connection point that simplifies sourcing matched bearing assemblies and hub components across platform swaps or custom builds.

This 30.5-inch length accommodates common Dana and full-float rear axle housings used in light trucks and SUVs, particularly those with widened track or altered suspension kinematics. Builders evaluating axle shaft specifications should verify spline count compatibility with their existing differential carrier and wheel hub assembly before ordering, as mismatched spline patterns will result in incomplete drivetrain engagement. Natural steel construction requires protection from corrosion via paint, powder coat, or other rust preventive when exposed to moisture or salt environments common in off-road use.
