The Jeep CJ series, which was produced from the 1940s through the 1980s, included a variety of transfer cases, depending on the model and year. One common transfer case used in Jeep CJ models is the Dana Model 300. Here are some key features and information about the Dana 300 transfer case:
Manufacturer: The Dana 300 transfer case was manufactured by the Spicer division of Dana Holding Corporation.
Years of Production: The Dana 300 transfer case was used in Jeep CJ models from the early 1980s until the end of the CJ series production in 1986.
Type: The Dana 300 is a gear-driven, cast-iron transfer case with a twin-stick shifter. This means it has separate shift levers for controlling the front and rear outputs independently.
Shift Configuration: The twin-stick configuration allows the driver to select between high and low range for both front and rear axles independently. This feature provides additional control in off-road situations.
Gearing: The Dana 300 transfer case has a 2.62:1 low-range ratio, providing increased torque for off-road crawling.
Compatibility: The Dana 300 transfer case was commonly paired with various transmissions, including the T-4, T-5, T-176, and T-18.
Upgrades: Due to its popularity and reputation for durability, the Dana 300 transfer case has been a favorite among Jeep enthusiasts. Some owners choose to upgrade their transfer cases with aftermarket components for enhanced strength and performance.

It’s important to note that the specific transfer case used in a Jeep CJ model may vary based on the year and edition. The Dana 300 is just one example, and earlier CJ models might have different transfer cases. Additionally, some Jeep CJ owners may choose to modify or replace their original transfer cases for improved off-road performance.
If you have a specific model year or edition of the Jeep CJ in mind, you may want to consult the vehicle’s service manual or contact Jeep enthusiasts and forums for more precise information about the transfer case used in that particular model.
