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.

There is several problems with this swap idea. 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.

Re: gearing change for a CJ2A
The ring and pinion are the same on a Dana 41 and 44, just stronger
carrier/bearings on the 44.
