2 Yes you can, but it is risky if the transfer case accidentally got engaged, kaboom!!

 

This isn't exactly a mod you want to half-***. If you do it, you want to do it all the way to get everything knocked out at once and reduce your chance of problems. But it is definitely a mod worth getting and worth the money. Huge difference in mine since I did the swap. Shop around for prices and brands though.

 

Tex what did you pay for everything parts labor etc

 

For my 2 sets of gears, install kit, and labor, about $1600.

 

2 sets of gears with rear DTT LSD $2300.

 

Technically, you can change just the rear gears IF you never put it in 4 wheel drive, but if you do, the flatbed guy will be going back to pick up your transfer case and probably both drive shafts off the side of the road after he winches your truck on board.

Personally, I'd save up and have both done. Going rate for gears, install kit an labor should range you anywhere from about $1250-$1600 depending on your area and where you go. Add a good LSD (Auburn or DTT) and you can add about $500-$600...

4.56s will help considerably given the fact you run 35s on a 4.7 V8, towing performance should improve dramatically...
