What is the purpose of changing the gear ratio?

Changing your gear ratio affects how your engine's power is delivered to the wheels. A 3.73 ratio is often chosen to improve acceleration, especially with larger tires, while still allowing for reasonable highway speeds.

Does this gear set come with installation hardware?

This product is for the ring and pinion gear set only. Installation typically requires additional components such as bearings, seals, and shims, which are usually sold separately. Refer to the manufacturer's installation instructions for a complete list of required parts.

What is the break-in procedure for new gears?

Proper break-in is crucial for the longevity of new gears. It generally involves a period of moderate driving with no heavy loads or hard acceleration, followed by a fluid change. Always consult the manufacturer's specific break-in procedure.
