ARB 728H111 Air Locker Differential Gear Set with Side Gears and Pinion Gears

The ARB 728H111 is a complete replacement gear set designed specifically for ARB Air Locker locking differentials. This precision-engineered component kit includes side gears and pinion gears that are essential internal components of the Air Locker system.

Key Features:

• Complete 6-piece gear set including side gears and pinion gears
• Forged nickel alloy steel construction for maximum strength and durability
• High-grade surface treatments for extended service life
• Designed to handle extreme forces within differential assemblies
• Features ARB's patented timed gear design for optimal locking strength
• Compatible with specific ARB Air Locker models including RD131 and RD132

ARB Air Locker gear sets are manufactured using forged gears typically found in heavy-duty commercial, race, and agricultural transmissions. The forged nickel alloy steel construction combined with refined gear-tooth geometry provides structural advantages of up to 30% over standard high-strength gears. This gear set is sold as a complete assembly and represents ARB's commitment to providing serviceable replacement components for their Air Locker differential systems.

Application: This gear set is used in ARB Air Locker differentials, particularly for Toyota 8" IFS applications with 50mm carrier bearings. Consult your Air Locker installation guide or ARB parts diagram to confirm compatibility with your specific differential model.
