I have an 87 pickup that i just got a SAS kit for due to my 83's frame breaking in half. Now i need to get it geared down, i am planning on only running 33's for a while and i know i could just get 4.88's and be fine, but id rather change up my t-case. I have seen the 4:70:1 t-case gears but i was also looking at the dual t-case setup considering i have an extra t-case. Any information on this stuff will help this will be driven around town and hitting the trails on the weekends. thanks

 

What is it you want to know?

Sounds like you know the options.

I recomend both. get the 4.7's, put em in the rear case, run the stock 2.28 in the front case, bolt it on. Gives you stock, low, and stupid low.
