Jeep 4.0 in 69 Barracuda

@75slant6 runs an AX-15 5-speed manual in his Duster behind a mild 360 Magnum and he likes it, the ratios go better with taller rear axle gears though (deep 1st, not very tall 5th) I think he's running 3.23s or 2.94s (?) They do have a pretty wide spread between gears especially 2nd-3rd but with a torquey street engine that shouldn't be an issue.

Thats kind of what I am thinking. My jeep wrangler runs 33in tires with 3.73 gears. A Automatic (AW4) XJ Cherokee runs 3.55 gears. And many manual trans XJs run 3.23 Gears and a AX-15.

My current trans is from a 4cyl YJ Wrangler (Peugeot BA-5) which had factory 4.11 gears in it. On my axle I am starting with the 3.73 gears and going from there. Once the car is road worthy, I will put a replacement trans based on options. I am really interested in speaking with 75Slant6 now hearing that user used a AX-15 which is the targeted trans of choice.

Thanks,
John
