What is the purpose of a ring and pinion gear set?

The ring and pinion gears work together to transfer power from the driveshaft to the wheels and change the gear ratio. Changing this ratio, known as re-gearing, can improve performance for larger tires, towing, or fuel economy.

What is included in the master installation kit?

The master installation kit contains all the essential components needed for a differential rebuild, including high-quality Timken bearings, seals, gaskets, and small parts like bolts and shims, ensuring a complete and proper installation.

Does this kit include everything needed for installation?

This kit includes the ring and pinion gears and all the necessary bearings and small parts for the differential rebuild. However, you may need specialized tools for setup and installation, such as a gear marking compound, dial indicator, and torque wrench. Refer to the manufacturer's installation instructions for a complete list of tools and procedures.
