ARB RD249CE Air Locker Differential 40-Spline Ford 10.25/10.5 Competition Edition

The ARB RD249CE Competition Edition Air Locker represents the pinnacle of selectable differential technology, engineered specifically for extreme off-road racing and high-performance applications. Designed for Ford 10.25" and 10.5" rear axles, this revolutionary air locker features a robust 40-spline design capable of handling the extreme shock loads generated by high-horsepower engines and oversized tires exceeding 40 inches.

Key Features:

• 40-spline configuration for maximum strength and durability in extreme conditions
• Selectable on-demand traction control via pneumatic activation
• Proven in competition including a 2017 King of the Hammers victory
• Compatible with Ford 10.25" and 10.5" rear differentials
• Engineered to withstand high-horsepower engines and large tire combinations

The RD249CE underwent years of rigorous research, development, and real-world testing in some of the most punishing off-road racing environments before its release. While engineered to meet the demands of top-flight rock racing competition, this air locker also serves serious off-road enthusiasts who require maximum traction and durability. The Competition Edition's 40-spline axle shaft compatibility provides the strength necessary to handle aggressive driving styles and extreme obstacles without compromising the selectable functionality that made ARB Air Lockers the industry standard.

Important Note: Use of this product in competitive racing environments voids the manufacturer warranty due to the severe and unpredictable nature of racing conditions.
