Hey guys, check this out... I posted soemthing on this board for a bud of mine....

http://www.broncoholics.com/support/...p?TOPIC_ID=108

And he sent me here...

http://www.bronco.com/lmb/timeline.shtml

See how under 1993, it says they put a NP 200 in the Bronco? And, it's got a 2.69 to one ratio for low?

What gives? Is this a typo? If not, can we use that 2.69 low and planetary setup to get a lower gearing out of our 200's?

And, if it's not a typo, then why is it so hard for manufacturers to manufacture low gearsets for the 200 and the 205?

Typo

I think it would be cost prohibitive to make low gears for the 200/205. You basically have 6 gears in the case, 3 for high and 3 for low. To change the diameter of one gear you'd have to change the diameter of another. But to change the diameter of that one, you'd have to change the third. To complicate matters, I believe the idler gear in the center is a cluster gear that has both gears on a common body so you'd be actually replacing 4 gears to get a lower ratio. To compound matters, you're limited by the inside dimensions of the housing.

You can manipulate a planetary gearset rather easily within the size constraints set by the factory.

And what do you think about the 205 theory in the Cronco?

And now he's changed his 205 hypothesis... Ah well.

JB Conversions is in the process of making a low gear set for the NP205. I talked to John last week and he said that they are several months away from marketing them. I'm on the call back list for a set. M1028

Default Dual master cylinder proportioning valves/distribution block

I actually just ordered a Super Short SYE from them for my YJ too...

Any idea of the gear ratio it'll be available in??

And, will you let us know when it's available?

I think it is going to be a 3 to 1 kit, but I'm not sure. M1028

Barry: I heard about that about a year ago... still waiting eh? Is there a way to contact him to get on said list? I've been dying for that kit, it's just right. Doubler is too much out here-- you end up either sliding down hills or flopping over ass over teakettle. Any idea on price yet?

Well, in talking with JB Conversions about the Ultra short 231 SYE, I ended up emailing this guy back and forth....

So there it is. I am still BS'ing with him... but that's the gist of it on the 205 low range.
