GM Performance ZR2 Ball Spline Half Shafts [17+ ZR2]

Chevrolet Performance ZR2 Ball Spline Half Shafts feature fixed inner and outer Double Offset Joints and a plunging Ball Spline Shaft, allowing for larger joint angles compared to production ZR2 half shafts, accommodating lifted or leveled 2017+ Colorado ZR2 models. These half shafts provide improved articulation while reducing feedback forces through the steering system during hard cornering and off-road events. Designed and validated for severe duty off-road events where speeds and loading conditions are pushed to extremes. Includes both Ball Spline Half Shaft, and wheels nuts for complete installation. 84429060
