Axle 31 Spline 36.0in 1.145in OD

The Strange Oval Axle 31 Spline 36.0in 1.145in OD is a precision-engineered axle shaft designed for high-performance and custom automotive builds. This 36-inch axle combines a 31-spline carrier interface with a 24-spline drive flange, making it suitable for builders working with specific differential and drivetrain configurations. The gun-drilled construction reduces unsprung weight while maintaining structural integrity, a feature valued in both street and competition applications where mass reduction impacts handling and acceleration.

Built from steel with shot peened and REM (Retained Enhanced Moisture) finishing, this axle delivers corrosion resistance and improved fatigue strength compared to untreated shafts. The 1.145-inch outer diameter provides a balance between strength and weight, critical for applications demanding consistent performance under load cycling. The 36-inch length accommodates full-width rear housing designs common in independent rear suspension conversions and custom chassis builds. At 8.9 lbs, the axle's moderate weight reflects the gun-drilled design philosophy—removing material where stress concentration is lowest without compromising load-carrying capacity.

This axle is engineered for builders selecting non-stock differential housings or custom gear ratios where OEM axles won't fit. The spline configuration allows integration with aftermarket lockers, limited-slip units, or bespoke diff setups. Buyers must verify carrier and flange spline compatibility with their specific differential before purchasing, as 31-spline carriers are less common than 28 or 35-spline designs in many platforms. Installation requires proper bearing preload setup and seal selection matched to your housing.

Sold as a single axle shaft, this is ideal for custom builds where independent axle replacement or repair is necessary, or for builders assembling a rear axle assembly from component parts.
