Np231 Vs Np242

Let’s traverse into the fascinating world of transfer cases, concentrating on two particularly renowned models – NP231 and NP242. They’re both impeccable choices, but your choice should be governed by your vehicle’s demands and your individual necessities. The New Process Gear (NPG) NP231, created by Chrysler, is a chain-driven transfer case, a distinguished option for lightweight 4WD vehicles. Stressing about power distribution? The NP231 ensues a 2.72:1 low range that makes it perfect for 4×4 trail conditions. On the contrary, the New Process Gear (NPG) NP242 is also under Chrysler’s creation and is renowned for its full-time traction. It includes a planetary differential, which, right off the bat, allows 48/52 front-to-rear torque split and ensures constant drive to all wheels. So, which one is the superior choice between the NP231 and NP242? Let’s unravel these mysteries together!

Navigating the NP231 Territory

The NP231 comes with a robust build, designed to withstand significant levels of torque, making it a favourite among off-road enthusiasts and light trucks owners. Their durability can be largely attributed to their chain-driven mechanism that allows for a smoother and quieter operation compared to gear-driven transfer cases. The NP231 offers a shift-on-the-fly feature, enabling drivers to change from two-wheel drive to four-wheel drive at speeds up to 55 mph. This saves considerable time and effort, providing a seamless driving experience, especially off-road.

One issue however with the NP231 is with its slip-yoke design. A design that though commonplace, has been known to falter in high articulation situations, potentially exposing the drive shaft and the transfer case to damage. But here’s some relief: The problem can be mitigated using a Slip Yoke Eliminator (SYE) kit. This modification not only eradicates the issue but also enhances the overall strength of the NP231 transfer case.

Advantages of Using an NP231 Transfer Case

– High durability, suitable for off-road usage
– Smooth and quiet operation thanks to chain-driven mechanism
– Shift-on-the-fly feature for seamless transition from 2WD to 4WD

Exploring the NP242 Landscape

The NP242 impresses right away with its full-time 4WD traction, which means the car is permanently providing power to all wheels. This is achieved through a differential mechanism, which helps in adaptively distributing torque between the front and rear axles depending on traction conditions. The NP242 offers several modes including 2WD, 4WD Part-Time, 4WD Full-Time, Neutral, and 4WD Low range.

While it is more complex due to the differential, the NP242 is significantly more flexible compared to the NP231. It allows the vehicle to be driven in 4WD mode on all types of surfaces without the fear of driveline binding, which can’t be said about the NP231.

Advantages of Choosing an NP242 Transfer Case

– Allows full-time 4WD making it versatile
– Provides different 4WD modes for various driving conditions
– Reduces driveline binding due to differential mechanism

Comparing NP231 vs NP242: Which Suits You Better?

The NP231, with its hardy build and shift-on-the-fly feature, is ideally suited for off-road enthusiasts or light truck owners who frequently face challenging terrain. On the flip side, the NP242, teeming with its full-time 4WD traction and differential mechanism, is more suited for those seeking versatility and stability, irrespective of the driving surface or condition.

Frequently Asked Questions

Q. Can I convert an NP231 transfer case to an NP242?

While it is technically possible to swap a NP231 with a NP242, it may require extensive modifications to your vehicle’s drivetrain. It is recommended to consult a professional before attempting such a procedure.

Q. Is it possible to run an NP242 in 2WD on dry pavement?

Thanks to the differential mechanism in the NP242 transfer case, it can be run in 2WD on dry pavement without risking driveline binding.

Final Thoughts

The duel of NP231 vs NP242 hands the gavel of decision to your vehicle specifics and driving requirements. The NP231 holds the fort of durability, especially for off-roading, whereas the NP242 triumphs in adaptability and full-time 4WD utility that helps in everyday driving. Neither wins nor loses in the comparison, only clarifying the assertion, ‘one size doesn’t fit all.’
