P.S. Trying to keep mileage & off-road preformance.

3:92

Hummmmmmmmmmmmmmmm.

Thanks, I'll look @t again.

I agree with MC. Go either 3.73 or 3.92. I ran 3.54's on a TH400, dana 300, 33BFG's and wish I could have regeared. It wasn't that bad, but kinda sucked off road.

Do U think it would be good W/that 3spd. (t-999)?

thanks,
Jim

I'm leaning towards the 3.73's

[Lifted79CJ7]

I guess it all depends on the type of driving you do. IF you mostly off road it, I would say go with 4.10's. If you use it for a good mix of both, I would say the 3.92's would be good, and if you only rarely get a chance to get off road, I would say 3.73's. Just remember that if you go too low you will have to get a different carrier as well to house the ring gear. I had 3.54's and it was great on the interstate, but wasn't all that great off road. If I was in your shoes I would go 3.92's.

Transmission 1st 2nd 3rd 4th 5th Rev
TF 999 2.74 1.55 1.00 2.20
TH 400 2.48 1.48 1.00 2.08

Hope this helps,
Jack

what axles are we talking here?

[rollbar]

Well Jack looks like w/the gearing on the spec's U provided the 3.90 would be better due to the fact I would have a 2.75 for (1st) & a 1.55 (2nd).

The D-30 has a 2.72 soI would need a new carrier to go w/a 3.90 if I'm correct.

These are the axles/gears that came w/the CJ8 project jeep.

Thanks,
RollBar

P.S> I still have the original 4 speed out of it & a 4 spd out of the 86' CJ7 so if I ever swap back I'll be in good shape.

[rollbar]

what axles are we talking here?

D-30=front

D-44=rear

For my CJ8 w/a nicely modified 360.

I have many amc-20's that I could use but........
