Gun Drilled Wide 5 31 Sp line 31.0in Long - Hi Te

The PEM Gun Drilled Wide 5 31 Spline 31.0-inch Long axle shaft is a high-tensile steel carrier designed for heavy-duty drivetrain applications requiring robust load capacity and precision spline engagement. This 31-inch axle features gun-drilling technology throughout its length, which reduces weight while maintaining structural integrity—a critical advantage in performance and off-road builds where unsprung weight directly impacts suspension response and handling. The Wide 5 bolt pattern paired with 31-spline carrier geometry makes this shaft compatible with wide-track rear axle housings commonly found in custom and high-performance vehicle builds.

At 7.25 pounds, this gun-drilled axle delivers material savings compared to solid designs without sacrificing torsional rigidity or spline shear strength. The natural steel finish requires proper corrosion protection—critical for longevity in wet or salt-air environments. The 24-spline drive flange accommodates standard differential flanges, while the 31-spline carrier end interfaces directly with modern limited-slip and locking differentials. Gun-drilling creates internal lightening passages that also improve heat dissipation, a benefit in sustained high-load scenarios like rock crawling or towing recovery.

This shaft is engineered for builders upgrading to wider axle housings or running higher-horsepower differentials where standard narrow-track axles become a limiting factor. Off-road enthusiasts, custom 4x4 fabricators, and high-performance street-truck builders rely on Wide 5 geometry to achieve the axle-track widths required for modern suspension geometry and tire clearance. The 31-inch length fits extended-wheelbase platforms and vehicles with custom rear-end positioning, making it a versatile choice for serious drivetrain builds.
