The Powertrax Differential is available as either the Powertrax Traction System for light trucks, SUVs and muscle cars or the Powertrax Lock-Right Full Locker for off-road and racing use. The Powertrax Traction System delivers extreme improvement in traction, allows maximum power to be delivered to both wheels from a stop or in high-g turns, eliminates wheel spin and is protected by a 2-year warranty. The Powertrax Lock-Right Full Locker is easily installed in existing case assemblies with no special tools or set-up equipment required, is used in extreme off-road situations requiring superior traction and high strength, eliminates wheel spin; also used for racing and other high-performance traction requirements. The Lock-Right is fully automatic and allows the outside wheel to rotate faster in turns, and in off-road use will always send engine power to the wheels that need it most. The Lock-Right Full Locker should be used for off-road or racing/high-performance only, where the Powertrax Traction System is more suited for daily drivers and less extreme performance.
