Where can I find some lower gears for my t case.. np 231 I'd like to have the 4:1

 

Teraflex makes a 4:1 low range kit for the NP231, it's quite pricey though iirc.

 

How much is pricey?

 

around 1100 iirc

 

yeah but that only replaces half of the case. a better way to get 4:1 is try to find an NV2410R transfer case from a jeep rubicon
the key word being find. 4:1 is going to be pricey no matter what but that's how I would do it

 

Agreed, didn't even think about that option, the Rubicon NP241 is a stronger case and has 4:1 low range in it already.

 

and an SYE from the factory.
