Gun Drilled Wide 5 31 Sp line 35.5in Long - Hi Te

The Gun Drilled Wide 5 31 Spline 35.5in Long - Hi Te axle from PEM is engineered for high-performance automotive builds where reliability and precision matter. This component is essential for custom suspension and drivetrain applications, particularly in drag racing, circle track, and extreme off-road platforms where factory axles cannot handle the demands of modified powerplants. Whether upgrading a dedicated race vehicle or building a street machine with serious power output, this gun-drilled axle addresses the need for reduced rotating mass and improved strength in one package.

Gun drilling removes material from the axle core while maintaining structural integrity, resulting in a lighter component that reduces unsprung weight and inertial load on your suspension. The Wide 5 bolt pattern provides a proven, rigid connection point compatible with both vintage and modern high-performance hubs, while the 31-spline design delivers torque capacity suitable for solid-axle platforms and custom differentials. At 35.5 inches in length with Hi-Te material specification—a proprietary high-tensile steel alloy—this axle combines weight savings with superior fatigue resistance. The precision manufacturing ensures concentricity and finish quality critical for sustained high-RPM operation.

Builders and fabricators working on custom rear housings, specialty sprint cars, or heavily modified street machines will find this axle ideal for solid-axle conversions and high-output applications. The 35.5-inch length suits mid-width and custom-width housings common in circle track and drag racing. Before installation, verify housing width and differential carrier spline compatibility to ensure proper fit and function. This is a core component investment for serious automotive enthusiasts committed to durability under extreme conditions.
