What is the benefit of a 4.56 gear ratio?

A 4.56 gear ratio generally improves your vehicle's acceleration and towing capability. It's often chosen when installing larger tires to help compensate for the added rotational mass and bring engine RPMs back into a more optimal range at cruising speeds.

Does this ring and pinion set come with installation hardware?
