im contemplating early next year either driving to marlins to get the dual adapter or possibly trading in my old t case for a 4.7 case. i like to hear some opinions on this. now you spoiled nor cal guys who just crawl granite all the time, keep in mind i live in so.cal. and the desert has alot of loose dirt and sand. all i know is at this point even with 4.88s the stock t case leaves a liitle to be desired thanks for the input

 

Duals will cost quite a bit more (donor t-case, drive shaft lengthening/shortening, etc.), but are worth the money in my opinion. With 4.7:1 you lose your stock low range. There are many situations when you won't need the 4.7 gears, and it would be nice to still be able to use your stock low range. With duals you retain stock 2.28:1, you can use 2wd low, and your double low is about 5.2:1. I say save up the extra $$ and do duals.

 

Duals. 'Nuff said. (You can always convert one of them to 4.7 later if you want anyway).

 

I live in Socal and use my dual cases all the time. You have more gear options with it...

 

Stock dual t'cases is lower geared than the single 4.7:1 set- 5.19:1. With my setup, the final drive ratio would change from it's current 109:1 to 98.9:1 - doesn't seem like a big difference, but it would be noticable.

One of the rarely mentioned benifits of dual t'cases is having a true 2x4 Low- a great gear for going slow over terrain thats rough but doesn't require 4x4.

There are times I'd be really unhappy being stuck on the trail in silly low. I shift back to low range between obsticals just to speed up the trail run.

After 3 years at 109:1, I'm ready for lower gears- the dual stockers have got me thru everything I've run so far, but the addition of a 4:1 gear set would have made parts of it much easier.......

 

you guys have raised some points i never thought of thanks for all the info i think im going to start looking for another t case to go duals

 

Another vote for duals. As said, one of the benefits is 2WD low for running around on fire roads, easy sections, etc. where you don't need 4WD but just low range. This reduces a lot of stress on your front drive train when you don't need to be in 4WD. Especially IFS with a locker up front.

With a 4.0, 4.7, or 5.0 in the rear case you have 20 forward gears compared to a dual stock cases where you have just 15 forward gears. Having a different range in each case gives you so many more options. Why go half way?? Go Ultimate!
