The Gun Drilled Wide 5 31 Spline 28.5in Long Hi Te axle shaft is a precision-engineered component designed for high-performance rear-end assemblies and custom vehicle builds. Built for serious enthusiasts who demand reliability under extreme load conditions, this 28.5-inch axle shaft integrates gun-drilled construction with a 31-spline carrier and 24-spline drive flange configuration. Whether you're upgrading a track car, drag racer, or heavy-duty off-road platform, this shaft delivers the strength and responsiveness required for aggressive power delivery and sustained performance.
Gun-drilled technology reduces shaft weight while maintaining structural integrity—a critical advantage when you're running substantial horsepower through a narrow differential. The 31-spline carrier interface provides superior load distribution and resistance to spline stripping, while the 24-spline drive flange ensures secure engagement with compatible gear assemblies. Manufactured from high-tensile steel with a natural finish, this shaft resists fatigue cracking and delivers consistent performance across repeated acceleration cycles, high-load cornering, and extended highway use. The 28.5-inch length accommodates most full-size and mid-size rear-end housings, making it a versatile choice for customization projects.
This axle shaft is ideal for builders upgrading OEM differentials or replacing worn components in performance-oriented platforms. Compatibility depends on your specific rear-end housing type and spline configuration—confirm that your differential accepts a 31-spline carrier and 24-spline flange before ordering. Installation requires proper bearing preload, seal management, and torque specifications per manufacturer guidelines; professional installation is recommended for optimal longevity. At 9 lbs, the gun-drilled construction contributes meaningful unsprung weight reduction, improving acceleration response and chassis dynamics in competition and street applications alike.
