So after my first trip with my Ranger I'm looking harder at doublers. Current setup is 4.0/np435/205, D60/14 bolt with 4.10s and 38s. I definitely need more gear and would rather not gear the axles.
I'm capable of re-gearing but would like to avoid it, if you've seen my build thread I'm using a 32 spline Dodge 60, I don't want to buy gears for the low pinion axle because if I break basically anything on it I'm buying a SD 60 and the gears wouldn't swap.
On to my question, what's everyone doing for 31 spline input doublers?
203/205. If I can source a Ford 203 the doublers are reasonably priced, I would prefer to have 3 speeds though so that's not my first choice. Also Ford 203s aren't falling out of every truck heading to the junkyard anymore.
Behemoth, well they are Behemoth. If it was made by a reputable company an underdrive utilizing Borg Warner planets would absolutely be my first choice. Is there anybody else building these that I just haven't been able to find?
NWF eco box. NWF has a great rep, I'm not big on extra machining due to using NP planets, anyone know what the machining entails and approximate cost to do so? NP planets aren't nearly as common as the Borg Warner stuff in my searching, plus the extra machining, makes it hard to put this as my first choice. The Titan just has a far higher price tag than I'm looking for with this build.
As far as I know DD/Duffy is out of business, Jed's website hasn't been maintained so not sure if they are in business either. Are there any options my Google-fu hasn't turned up that are Ford friendly?
