gearing change for a CJ2A
Some years back I had a '47 CJ2A, and am currently considering getting
another (a '48). My recollection is that the stock gearing was somewhere around 5.13 or so, and I'm wondering whether it's possible/feasible to replace those with maybe a 3.08 or even 2.73 set for better mileage and the possibility of doing highway speeds. Are parts available? Can it be done without swapping axels? Thanks. Joe |

First of all, the orignal engine would not pull it too well with a 4.10 vs even a 3.08, next it has a Dana 25 front axle that is only avalible in 4.27, 4.88, 5.38, and 6.17 to 1 and last the rear axle should be a Dana 41 and good luck finding taller gears for that one (or even any gears) Typically D41 are swapped out to D44 as D41's had 2 piece 10 spline axles too. ----------------- TheSnoMan.com |

The ring and pinion are the same on a Dana 41 and 44, just stronger

Re: gearing change for a CJ2A
Thanks for those tips. Overdrive sounds like the way to go. I seem to recall
that Advance Adaptors used to offer one. I'll have to check them out.
