Ok sorry in advance cause this has probably been dicussed to death on here already but here it is anyway. I'm honestley not at all a newb to wheelin and building rigs but never knew anyone around who had a twin tcase setup. Does this setup independantly controll fr and Rr gear selection for the tcase gearing so you have more crawling selection of gears or what? IDK cause I never messed with one or had someone explain its function to me.

 

Twin stick allows separation between 2wd and 4wd function. Dual cases allows a normal gear reduction and a secondary reduction thru the second case and the transfer is done thru the second case.. It essentially adds a SUPER low gear set. Thus why you have two shifters with dual cases. Much better to differentiate control between easy to severe crawling terrain.

 

Thanks for the info, now I know what's its correct function is.
