Over/underdrive unit. You really shouldn't add a gear in there, would not be worth it. A over/underdrive unit or a ZF tranny would suit you perfect.

What do you mean? Can you elaborate a bit?

I found a neat O/U drive unit today from Gear Vendors. Will bolt right up to my NP435. All I have to do is shorten my divorce mount drive shaft. But the kicker is this......only 20% reduction in RPM. That means I go from 3000rpm to 2400rpm. At this point it is not worth it at $2700 for the unit!

It may be better to put a nice Automatic in it with a B&M shift kit. Or somthing of the sort......

Your thoughts?

well, the cheapest and easiest would be an AOD, there a re companies which build bulletproof AOD's, someone will chime in and help me out with a name. The gear venders unit was what i was talking about. 20 percent reduction is pretty good, there is only a 29 percent drop from o/d in a E4OD, and i think they are the highest.
