CJ5- Shortest transmission

Fullywrecked · Sep 29, 2009

I would do a 4l80e and a 203/205 doubler. Tough setup there. Then spring it over with 4" lift springs.:beer:

Sounds like a plan, but he doesn't want to lift it anymore than it already is. I'm trying to convince him to go with the Dana 300, and upgrade the axles while he is at it.

Yes cj5's from 72-79 (I believe) came with the T18 as an option. Most of them were 4:1 ratio. In my CJ5 I have a 79 T-18 from a cj5 with a 258 and it had a 6:32:1 first gear. If you want it for gearing look for the Ford T-18 and most of them have the 6:32 first gear. I believe you want a 7" stickout input shaft for most cj conversions. You can still buy new input shafts if you need the short one (which you will in a CJ5). :beer:

T18 is 4:1 first and T18A is 6.32:1 (that should be what's in my '82 Stepside)
