Description

The ARB 728K101 is a gear set for differentials, specifically designed for K10 Series differentials. It is described as a crucial component for enhancing a vehicle's drivetrain performance by effectively transferring power from the engine to the wheels. This gear set allows for adjustment of the gear ratio, which can lead to higher RPMs in top gear, making it suitable for fine-tuning performance. ARB, a trusted name in the 4WD community since 1975, manufactures this durable and effective accessory for modified vehicles and challenging terrains.
