The Detroit Speed 17-Spline Rear Half Shaft Kit provides modern CV reliability for C2 and C3 Corvettes equipped with DECAlink™ rear suspension systems and stock 1963–1979 differentials. Designed for builds up to 400 horsepower, this kit replaces failure-prone factory U-joint half shafts with a refined CV design.

Ideal for street performance and restomod applications, it delivers smoother articulation, increased durability, and improved driveline confidence without sacrificing compatibility with factory-style 17-spline differentials.

ENGINEERED FOR STRENGTH & RELIABILITY

Factory Corvette half shafts place suspension loads directly through U-joints, creating a known weak point under increased power and articulation. Detroit Speed eliminates this limitation with a modern CV configuration engineered specifically for DECAlink™ rear suspension systems.

The inclusion of forged 17-spline stub axles ensures proper engagement with stock 1963–1979 Corvette differentials. Rated to 400 horsepower, this system delivers improved durability, smoother torque transfer, and long-term reliability for performance street applications.

BOLT-IN CONVENIENCE
