What is the purpose of a 5.38 gear ratio?

A 5.38 gear ratio significantly increases the torque multiplication at the wheels compared to a stock ratio. This is beneficial for larger tires, as it helps restore lost acceleration and improves towing or hauling capability by allowing the engine to operate in a more efficient RPM range.
