What is the benefit of a 3.73 gear ratio?

A 3.73 gear ratio generally offers a good balance between acceleration and fuel economy. It provides improved off-the-line performance compared to taller gears (numerically lower ratios) and better highway cruising than shorter gears (numerically higher ratios), making it a popular choice for many applications.
