Wanting to swap about my 4.10 in my v6 just dont know who to order from and this may seem like a stupid question would I need to order two of them because front and rear?

 

You can order from Marlin Crawler. Yes, you will need to order two, one for the front differential and one for the rear. The front will be a 7.5 inch because it is ifs in the front, 8 inch in the rear. Also, you may want to consider adding a locker in now if you haven't yet but plan on it in the future, since you will have the 3rd member out already.

 

trail gear is probably cheaper. they use Yukon in a trail gear box. I have set-up a couple sets of them and all of them are still moving fine.

 

OHH YEAH don't for get the setup kits and don't just buy gears lol

 

Any one wanna give me links so I don't order the wrong thing xD

 

IFS front is 7.5"
Rear IFS or SFA is 8"

7.5" will be more expensive and a bigger pita to do.

If you are SAS then you can just get two 8" R&Ps and the install kits.
