The NP205 transfer case is a super heavy, cast iron, heavy duty gear driven transfer case. The NP205 gear driven transfer case is considered by many to be the bulletproof. It was supplied in many GM, Ford, International and Dodge full-size trucks. It’s weight is prohibitive to almost anything except original applications. The New Process Model 205 is a two-speed, part time, cast-iron transfer case. Discontinued in 1985, our inventory includes a new process 205 (np205) for sale.
Many experts say this unit is the strongest transfer case ever built! It is gear driven and it has a 2:1 low range ratio.
Applications:
All GM NP205 cases 1971-1985 had a 8 bolt “racetrack” bolt pattern
All GM NP205 Cases 1986-up had a 6 bolt circular bolt patternThe Ford NP205 transfer case uses the 6 bolt circular bolt pattern . It has a left hand drop (driver’s side). It is supplied with a 31 spline female input.
Dodge NP205 Transfer Case
The Dodge NP205 transfer cases are mostly an 8 bolt pattern like the early Chevy. Some late units had the 6 bolt circular pattern. These units all have a right hand drop. Most are supplied with a 23 spline male input shaft and used with a coupler.
The low down on these transfer cases is based on unbelievable durability by way of materials that weigh a lot and are very durable. There was nothing subtle about it. It is large in size, using a cast iron case: no high tech light weight materials like aluminum alloys. Aluminum is the preferred material for both transmissions and transfer cases now a days for weight saving purposes.
The internal parts were anything but subtle too. Tremendous gears and shafts, by any standards, using gears to drive the ”transfer” portion instead of a chain. Chains drive 95 plus percent of transfer cases and AWD units in modern vehicles. Most of the new cases are computerized.
Very few failures occured to the large metal parts. Simply put, most failures were due to loss of lubrication. Why? Many of the vehicles that this component was offered in were so trouble free, the lubrication levels were often neglected. That long ago, there was no such thing as ”lube places”, so plenty of items like transfer cases and differentials were not checked for lubrication level as often.
Another possible failure problem is not isolated to this transfer case alone. The issue is water. Any drive-line component that gets water mixed into the lube is failure prone. Most of the time this is a problem for 4 wheel drive enthusiasts. Although many four wheel drive enthusiasts know this can be an issue, and check all drive-line components after an outing.
Based on the strength alone, many 4×4 enthusiast have developed custom setups to adapt the NP205 to a specialized application taking advantage of it’s durability. Never doubt the imagination of an enthusiast and what concoction can be devised to go off-road. Take a minute and call now about a New Process 205 for sale. We have exactly what you are looking for.
