How do I know what NP205 I have?

The NP205 transfer case is a popular component found in many four-wheel-drive and all-wheel-drive vehicles. Knowing how to identify the specific NP205 model you have is important for maintenance, repairs, and upgrades. This article will guide you through the steps to determine the NP205 transfer case in your vehicle.


Identifying the NP205 Transfer Case


To identify your NP205 transfer case, you'll need to look for the identification tag or casting number. This information is typically located on the side or bottom of the transfer case housing. The tag or number will provide details about the specific model and features of your NP205.



  • Identification Tag: The identification tag will have the transfer case model number, such as NP205, as well as other details like the gear ratio, part number, and serial number.

  • Casting Number: The casting number is a unique code stamped directly onto the transfer case housing. This number can be used to cross-reference the specific NP205 model.


Once you have the identification tag or casting number, you can use that information to research the details of your NP205 transfer case, such as its gear ratios, input/output configurations, and compatible vehicle models.


Determining the NP205 Model


The NP205 transfer case was used in a variety of vehicles, including Jeeps, Chevrolet, GMC, and Dodge trucks, as well as some SUVs. The specific model can vary based on the vehicle application, so it's important to have the correct identification information.


Some common NP205 models include:



  • NP205 4WD: This is the standard NP205 transfer case found in many 4WD vehicles. It typically has a 2.72:1 low-range gear ratio.

  • NP205 AWD: The AWD version of the NP205 is designed for all-wheel-drive applications and may have different gear ratios or features.

  • NP205 HD: The Heavy Duty (HD) NP205 is a more robust version of the transfer case, often used in larger trucks or vehicles with higher towing capacities.


Knowing the specific NP205 model in your vehicle will help ensure you get the right parts and accessories for maintenance, repairs, or upgrades.
