Detroit Speed Axle Half Shaft Kit, ZR12 1200HP Rated 070651DS

The Detroit Speed ZR12 Rear Half Shaft Axles deliver modern reliability and elite torque capacity for high-performance C2 and C3 Corvette builds. Designed specifically for use with Detroit Speed’s DECAlink™ rear suspension and ZR12 IRS Differential, these CV axles eliminate the limitations of factory U-joint half shafts.

Engineered for performance-driven applications up to 1200 horsepower, they provide smooth power delivery, increased durability, and refined driveline operation for street, Pro Touring, and competition builds.

ENGINEERED FOR STRENGTH & RELIABILITY

Factory Corvette half shafts place suspension loads through U-joints that were never designed for modern horsepower. Detroit Speed replaces this outdated architecture with a contemporary CV design, dramatically improving strength and long-term durability.

Constructed from premium 300M alloy steel, these half shafts are engineered to withstand extreme torque loads while maintaining smooth articulation throughout suspension travel. The result is increased reliability, improved driveline refinement, and the confidence to harness serious horsepower without compromise.

BOLT-IN CONVENIENCE

Engineered for seamless compatibility with Detroit Speed DECAlink™ and ZR12-equipped Corvettes, these half shafts install directly without modification.
