Fusion semi-float axle shafts are forged from 4130 chromoly, heat treated and induction hardened for maximum strength and durability. The material selection and heat treat process is a result of years of experience and hundreds of thousands of customer miles on our semi-float rear axles. The combination strikes an ideal balance of strength and hardness, while minimizing failures. Over 40% stronger than OE shafts.
