Axle 31 Spline 30.5in 1.145in OD

The Axle 31 Spline 30.5in 1.145in OD by Strange Engineering is a precision-engineered rear axle shaft designed for high-performance and modified vehicles requiring robust drivetrain components. Built for enthusiasts and mechanics tackling serious suspension upgrades, custom differentials, or competition-level builds, this axle delivers the structural integrity needed to handle elevated torque loads and demanding driving conditions.

The 31-spline design provides superior load distribution and engagement compared to weaker spline configurations, making it essential for street rods, drag cars, and heavily modified street machines. With a 1.145-inch outer diameter and 30.5-inch length, this shaft is engineered to precise tolerances that ensure reliable fitment and smooth operation within your differential housing. Strange Engineering's manufacturing standards deliver straightness and concentricity critical for eliminating vibration and ensuring even power delivery across both wheels during acceleration and cornering.

This axle is ideal for vehicles equipped with higher-horsepower engines or modified gear ratios, making it a great choice for performance enthusiasts. Its material composition and heat-treat process are designed to withstand repeated shock loads from launch and hard shifting. While it is commonly used in high-performance applications, specific compatibility should be verified based on individual vehicle requirements.
