What is the purpose of a 4.27 gear ratio?

A 4.27 gear ratio generally provides more torque to the wheels, which is beneficial for off-road driving, especially when using larger tires. It allows the engine to operate at lower RPMs at highway speeds compared to a numerically lower ratio, though it will increase engine RPMs at any given speed compared to a stock ratio.

Does this ring and pinion set come with everything needed for installation?
