Understanding the Transfer Case in Your Jeep

From 1950 to 2019, the Jeep brand has undergone a myriad of changes. Over the course of almost 70 years, there have been several iterations of transfer cases, manufactured by different companies, each designed to enhance the driving experience. This article aims to demystify the different transfer cases found in Jeep vehicles, highlighting the key features and models that have defined Jeep's legacy.

Featuring Transfer Cases in Jeeps

Whether you drive a vintage Jeep or a modern model, understanding the transfer case is crucial for maximizing the vehicle's performance and durability. The transfer case essentially transfers power from the engine to the axles, providing a range of driving modes to suit various terrains and conditions. Here is an overview of the different transfer cases that you might encounter in your Jeep:

The Dana Transfer Case

The Dana transfer case is a classic and widely recognized name in the world of four-wheel drive vehicles. Introduced back in the early days of Jeep, Dana transfer cases have been a staple in numerous models, with several iterations that cater to different configurations and needs. Common Dana transfer cases found in Jeeps include:

Dana 18: This single-speed transfer case is a simple and robust design, ideal for vehicles that require straightforward four-wheel drive functionality. Dana 20: Another single-speed option, the Dana 20 also includes a locker for added traction when needed. Dana 300: This model offers more complex gear ratios and a single-speed configuration, suitable for light-duty off-roading.

These Dana transfer cases were widely used in Jeeps and continue to be respected for their reliability and performance.

The NP200 Transfer Case

The NP200 transfer case is another widely recognized brand, particularly favored by both Jeep enthusiasts and off-road adventurers. Unlike the simple Dana designs, the NP200 offers a more sophisticated approach to power transfer. Here are some key features:

Two-speed capability: The NP200 allows for low-range and high-range operation, providing versatility in different driving conditions. Economy mode: This feature helps improve fuel efficiency in regular driving conditions.

Models such as the NP207, NP228, NP229, and NP231, all featuring variations of the NP200 architecture, are popular among older Jeep models, offering a balance of performance and reliability.

Modern NP241 and NV247 Transfer Cases

Whilst the original NP200 transfer cases have been around for decades, contemporary designs such as the NP241 and NV247 have also made a significant impact in modern Jeeps. These transfer cases represent a blend of older proven technologies and modern advancements. Here are key points about these models:

Enhanced durability: These modern transfer cases are built to last, with improved materials and engineering. Electric locker integration: The NP241 and NV247 models often come with integrated electric lockers, providing precise control over traction.
