GForce Renegade axle shafts offer big league strength and performance at a fair price point. They're direct replacements for your factory half-shafts and are designed for cars with everything from mild bolt-ons to those running superchargers and turbos. CNC-machined from proprietary aerospace billet alloy, Renegade axles feature upgraded spline counts on the axle bar and CV joints—providing more engagement. This allows for larger diameter bars equaling more strength, as well as more travel and increased operating angle over OEM CV joints. GForce Renegade axle shafts are a leap above entry-level, with hand-built assemblies utilizing premium materials and carefully controlled processes. Order the pair recommended for your vehicle application. Features include: * Anti-wheel hop technology—significant reduction during hard launches * Direct bolt-in fit and finish * 31-spline severe-duty CVs * Stronger one-piece CNC-machined inner and outer stubs * Powdercoated axles for corrosion protection * Black E-coat finish on inner and outer stubs to protect against harsh conditions, without impeding spline engagement
