T4-T5 Which is stronger?

I currently have a choice of 3 trannys to put behind the Iron Duke in the 81 7 project I'm working on. I have a SR4, T4 & a T5. I know the SR4 is weak so if you had a choice between a T4 or T5 which one would you use? is there any strength differances between the 2?

It will be stricly a trail Jeep so the OD of the T5 isn't really a issue. I also have all the driveshafts & X-cases for them all so either one will be a easy swap.

One other stupid question because of a memory error [img]images/graemlins/crazy.gif[/img]
What year did they switch to the wide track axles in CJs?

T4/5 same trans basically, so I can't imagine any difference in strength. WT=1981

I think the widetrac started in 1982 in the CJ-7 & 8. They used narrow up to the end in the 5.

Re: T4-T5 Which is stronger?

Strictly a trail jeep? How about an SM465 with NP208? You'll get the 6.55:1 first fo the SM465 and 1.7 (approx) of the NP208, which although is chain drive will easily last behind the Iron Duke. It'll bolt on, be strong, have a low gear, and is easy to find, just look for 1981-1989 Chevy trucks 1/2 and 3/4 ton.

Yes I remember that from another post I asked about SR4 replacements. [img]images/graemlins/smile.gif[/img] I have that filed away for future work and maybe even a SBC if I don't like the 4. But right now I have to use what I have to keep within budget. [img]images/graemlins/frown.gif[/img]

Re: T4-T5 Which is stronger?

Jeepn can you give me some more info on that sm465 swap? I know i can get a t5 bell housing modified to fit an sm465 but i havn't figured out a t-case option unless i can find a sm465 to d20 or d300 adapter for cheep. Help me out, i want a granny 4 speed in my postal project for cheep, it's a dirt cheep budget build up.

Re: T4-T5 Which is stronger?

Just grab the bellhousing that it comes with, it's usually thrown in with the tranny. As to the transfer, I do not know of a cheap one to fit a jeep of that length (I think the NP208 is the shortest, could be wrong though), except maybe to sit the engine forward more. It's a DJ, so the frame should be 4" longer than it's CJ counterpart. There is also plenty of room in front of that GM151, I have several sitting in the yard with that engine in it.
