Default NP203/NP205 Doubler

Who all runs them and how do you like them? I was thinking about putting it in the blazer when i switch my automatic in. Is it really a good combo for a mud truck or is it better for crawling?

i'm in the process of collecting parts for my doubler. i have the 205 just looking for the 203 and adapter. my truck will be capable of doing both mudding and crawling. the strength is a big plus and the 4:1 low gearing is awesome for crawling.

Exclamation 203 doubler parts

I have the major factory components for a doubler. i have a complete 203 as well as another grb and the adapters to th350 trannys. Let me know if you need these parts. I'm not going to use them. Not doing the doubler in my project.

Skip the doubler and go with a LoMax 3to1 205 case and gears, same price as all the doubler parts and stock driveline length. This settup is stronger than an Atlas.

Mine is going in this weekend, did a manual VB 400 too..

If I were buying it again I would go for a NP241/NP205. You get more gearing options since the 241 low range box is 2.72:1. Only tricky part is that one of the shifters collides and you have to relocate it to the rear of the 205.

d.d. machine sells the setup its not bad price-wise either.
