Gun Drilled Wide 5 31 Sp line 35in Long - Hi Test

The Gun Drilled Wide 5 31 Spline 35in Long - Hi Test axle shaft is engineered for high-performance vehicles running wide 5 bolt patterns, particularly drag racing, circle track, and street rod applications where extreme load capacity and durability are non-negotiable. Built for drivers and fabricators who demand reliability under punishing acceleration and cornering forces, this axle shaft fills the critical role of transferring engine power to the wheels while withstanding the shock loads inherent in modified and competition vehicles. Whether you're upgrading a vintage hot rod, competition racecar, or high-horsepower street machine, a quality axle shaft is the foundation of safe, consistent drivetrain performance.

This gun drilled design reduces rotating mass and weight—critical advantages in performance applications where every pound matters for acceleration and handling. The 31-spline configuration provides superior torque capacity and engagement surface compared to lesser spline counts, distributing load across more contact points and reducing stress concentration. At 35 inches long with Hi Test material specification, this shaft is built from high-strength alloy steel that resists fatigue cracking and torsional failure under sustained high-horsepower conditions. Gun drilling—the process of drilling a precise axial hole through the shaft—improves weight reduction while maintaining structural integrity, a hallmark of purpose-built racing components.

This axle shaft is ideal for builders working with wide 5 rear ends common in vintage American muscle cars, hot rods, and dedicated race vehicles. Installation requires proper alignment and balancing to ensure smooth operation and longevity; professional installation or fabrication experience is highly recommended. Verify your vehicle's existing spline count, bolt pattern, and length requirements before ordering, as axle shafts are precision-fit components. Pair this with quality bearings, seals, and a properly set differential for maximum lifespan and performance.
