We’ve compiled a list of all the different Chevy transfer cases that have been used over the years, and what vehicles they were used in. This should make it easy for you to find the right transfer case for your Chevy truck or SUV.

Chevy has used a few different types of transfer cases over the years. The most common type is the NP205, which was used in a variety of Chevy trucks and SUVs from 1967-1991. The NP205 is a gear-driven transfer case, meaning that it uses gears to send power from the engine to the wheels.

This makes it very strong and durable, but it also means that it’s not as smooth as some other types of transfer cases. Another type of transfer case that Chevy has used is the NP263HD. This was used in some heavier duty trucks and SUVs from 1992-2007.

The NP263HD is similar to the NP205, but it has an extra set of gears that make it even stronger. This makes it ideal for heavy duty use, but it can also be a little bit rougher than other types of transfer cases. Finally, there’s the NVG246 Transfer Case.

This was introduced in 2008, and it’s been used in a variety of Chevrolet trucks and SUVs since then. The NVG246 is an electronically controlledtransfer case, meaning that it uses sensors and computers to control how power is sent to the wheels. This makes it very smooth and efficient, but it also means that it’s more complex than other types of transfer cases.

Are All Gm 246 Transfer Cases the Same?

No, all GM 246 transfer cases are not the same. There are slight variations between different model years and between different vehicles that used the GM 246 transfer case. For example, the 2003-2007 Chevy Silverado and GMC Sierra 1500 both used the GM 246 transfer case, but there are some differences in the way they were built.

The biggest difference is that the 2003-2007 Silverado and Sierra 1500 both had an electric shift motor mounted to the side of the transfer case, while later models switched to a push-button shifter inside the cab. Other than that, there are relatively minor differences between different model years and between different vehicles that used the GM 246 transfer case.

How Do I Know If My Transfer Case is Compatible?

If you’re considering swapping out your transfer case, it’s important to make sure that the new one will be compatible with your vehicle. There are a few things you’ll need to take into account, including the make and model of your car, as well as the year it was manufactured. You’ll also need to know what type of transmission is in your car.

With that information in hand, you can then start looking at compatible transfer cases. One way to find out if a particular transfer case will work with your car is to consult your vehicle’s owner manual. In most cases, there will be a section that lists compatible transfer cases for your specific make and model.

If you don’t have access to an owner manual, you can also check online forums or ask knowledgeable friends or family members for help. Once you’ve narrowed down your options, it’s time to start shopping around! Keep in mind that even if two transfer cases are technically compatible, they may not be a perfect match.

For example, some models may require minor modifications in order to fit properly. In other cases, two seemingly identicaltransfer cases may have slight differences that could affect performance. That’s why it’s always best to do your research before making any decisions – this way, you can be sure you’re getting exactly what you need.

What 3 Types of Transfer Cases are Available?

There are three types of transfer cases available: gear-driven, chain-driven, and gerotor. Gear-driven transfer cases are the most common type used in vehicles. They use gears to engage the front and rear axles, providing power to both wheels.

Chain-driven transfer cases are less common, but they offer a smoother ride and less noise. Gerotor transfer cases are the least common type of transfer case. They use a series of discs and rotors to engage the front and rear axles, providing power to both wheels.

What Vehicles Have Np241 Transfer Case?

The NP241 transfer case was used in a variety of vehicles including the Chevrolet S-10 Blazer, GMC Jimmy, Oldsmobile Bravada and Isuzu Trooper II. It was also used in some Dodge trucks and SUVs including the Dakota, Durango and Ramcharger. The NP241 is an aluminum case with a chain-driven transfer case.

It features two speed ranges: high and low. The low range is typically used for off-road driving or towing while the high range is for normal driving conditions. There are two versions of the NP241: theNP241C which has a center differential and the NP241D which does not have a center differential.

  1. I have GMC K2500 SLE with 5 speed transmission and 241 C transfer case.
    Can I upgrade to a newer stronger transfer case or do I need to stick with 241 replacement ?

    1. Yes, it is possible to upgrade to a newer, stronger transfer case instead of sticking with a direct replacement of the NP241C. However, there are a few important considerations:

      Compatibility with the Transmission: Ensure that the new transfer case is compatible with the 5-speed transmission in the GMC K2500. This includes checking spline counts, input shaft size, and the physical mounting interface.

      Electronic vs. Manual Operation: The NP241C is a manually-operated transfer case. If considering an upgrade to a newer transfer case, especially those that are electronically controlled (like the NP261HD, NP263HD, or others), it’s essential to consider the additional requirements for electronic integration and control.

      Adaptation Requirements: Depending on the chosen transfer case, there might be a need for custom adaptations. This could include modifications to the driveshaft, linkage adjustments, and potentially electronic modifications if moving to an electronically controlled transfer case.

      Vehicle Use and Requirements: Consider the intended use of the vehicle. If the vehicle is used for heavy towing, off-roading, or other demanding activities, a heavier-duty transfer case like the NP261HD or NP263HD could be more suitable. These models are designed for higher torque applications and offer increased durability.

      Expert Consultation: Given the technical nature of this upgrade, it would be advisable to consult with a transmission and drivetrain specialist. They can provide specific recommendations based on the vehicle’s configuration and intended use.

      In summary, upgrading to a newer and stronger transfer case is feasible, but it requires careful consideration of compatibility, vehicle use, and potential modifications. Consulting with a specialist will ensure that the upgrade meets the specific needs of the vehicle and owner.
