Welcome to the board,

Tell us about your truck and its intended usage.

The durability of the 700r4 tends to spark debate. A stocker behind a torquey big block and heavy foot is not going to last especially if you tow heavy loads, run big tires, and use high gearing. They can be built to last but it can get pricey and finding a competent builder who knows the weak points and how to build them can be tough to find.

If you were to switch to the 700r4 either get the np208 transfer case that comes with it or adapt to the np205. No sense staying with the np203.

This all tends to add up $$ so do your homework. Good luck.
