NP 203-205 T-Case Adapter.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, so I have heard that you can stick the NP 203 planetaries toa NP205 then bolt all that to yer tranny, and have yerself a dual T-Case 4-by.... in the end it leaves you with a fairly bulletproof 6:1 crawl ratio....if this is the case, does anyone know where I can pick up an adapter, an for how much? and also, how much work is it to do suck a conversion?? I am building a new TH400 for my rig and I was gonna go with the NP205 cause Im tired of the 203 chain driven crap...and when I heard of the dual setup, I got excited, so any info would be much appreciated!!

off road design does sell this kit you basically use the range box out of the 203 mated to a 205 for ultra low crawling. I recently picked up a twin stick 205 that i'm swapping in to replace my 203 and thought about doing a doubler but think i 'll try it out with just the 205 in moab first then decide. try coloradok5.com for more info alot of guys on there have done the swap
