What is a transfer case mainshaft gear?

The mainshaft gear is a crucial component within your Jeep's transfer case. It works in conjunction with other gears to transmit power from the transmission to the front and rear axles, enabling four-wheel drive.

What does '6 splines and 29 teeth' mean for this gear?

The '6 splines' refer to the six grooves on the shaft that engage with other components, ensuring a secure connection. The '29 teeth' is the count of gear teeth, which determines how this gear meshes with other gears in the transfer case to achieve the correct gear ratios.

Does this gear come with any hardware for installation?

This Omix Dana 18 mainshaft gear is sold as the gear itself. Installation hardware, such as seals or snap rings, is typically not included and may need to be sourced separately if required for your specific repair.
