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

A 4x4 and traction go hand-in-hand; however, standard (open) differentials allow each wheel to turn independently to eliminate binding in turns. Off-road, this becomes a problem as engine power takes the path of least resistance—to the wheel with little or no traction. Limited slip differentials offer some improvement, but too often the slipping is not "limited" enough to maintain forward progress. Automatic locking differentials also have disadvantages; noisy when disengaging, they can also upset on-highway driving characteristics. Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ a 12 V ARB air compressor (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential. When activated, the Air Locker prevents the differential gears from rotating and the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional open differential. ARB Air Lockers are available in over 100 configurations for a wide range of vehicles and can be installed in both front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required, apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and operate other equipment. Additional features of ARB Air Lockers include: * Vastly improved traction means less reliance on momentum, reducing the likelihood of vehicle damage * Easy, convenient operation without leaving the comfort and safety of the driver's seat * Ultra durable and extremely strong; only the highest quality materials used in construction * Patented gear technology and 2-piece design ensures optimal locking strength * Forged gears provide superior strength and durability * Incredibly simple, yet effective, design employs minimal moving parts for maximum reliability * Thoroughly tested and proven * Most sold as kits with differential, activation switch, solenoid valve, air line, and bulkhead fittings * Front and rear Air Lockers available for most makes and models * For 4WD and 2WD applications * Easy maintenance; no special additives required * Also offered in ARB Traction Packs that include two Air Lockers, a compressor, and accessories for tire inflation
