Air Locker Differential Ford 10", 40 SPL, RD249CE

The RD249CE Air Locker has been designed around the requirements of top-flight rock racing requiring the features of a selectable locker with ability to use 40-spline axle shafts to withstand the shock load caused by high horsepower engines and 40+ tires. The RD249CE carries the standard 5-year warranty. While this product was designed to withstand the demands of competition racing, the use of this, or any Air Locker, in competition voids the warranty due to the severe and unpredictable nature of racing.
