Product Details

The ARB 728K021 is a replacement differential gear set designed for ARB Air Locker systems. This precision-engineered gear set includes K2 side gears and K1 pinion gears, which are critical internal components that work together to enable the locker's engagement and disengagement functions.

Key Features:

  • Genuine ARB replacement gear set for Air Locker differentials
  • Includes K2 side gears and K1 pinion gears
  • Precision-manufactured for proper fit and reliable operation
  • Designed to restore full Air Locker functionality
  • Direct replacement for worn or damaged internal locker gears

This gear set is an essential service part for maintaining ARB Air Locker performance. When internal gears become worn or damaged, replacing them with genuine ARB components ensures your differential locker continues to operate as designed, providing maximum traction when you need it most.
