Ring Gear Install

A change in axle gearing can help compensate for larger tires and restore a good bit of the engine efficiency. A simple calculation can be done to determine the new axle ratio needed to restore the original cruising rpm while running the new tires. It’s also not uncommon to slightly over-compensate on the gearing as the heavier tires rob a bit more power and can benefit from a little more drop in gearing (numerically higher) in the axles.
