Hello all, I've searched to find no answer on the internet for the specs On my 1949 Chevy Dually axle. Anyone interested in chiming in? I may run it for a year or two with the old drum brakes. Just want to know what I have. I appreciate any help offered. Attached are a few pics.
Bignscar My 51 6400 has that same 2-speed axle works fine !
That's good to hear, I'd really like to keep the rear axle. What's your power train set-up? My goal is to be able to drive it a lot Have a smooth ride on the freeway Pull a 5th wheel camper Add 4wd Possibly go big block, like 427 or 454 eventually I have a 5.3 4wd powertrain I can use now though Brought it home today.

Nice truck. 4wd front axle gets sort of high off the ground because stock frame does not have enough arch to allow for front driven axle to clear. Can be done OK, just have to allow for that. Look at factory late ‘50’s 4wd conversions.
'37 GMC T-18 w/ DD 4-53T, RTO-610, 6231 aux., '95 GMC running gear, full disc brakes, power steering, 22.5 wheels and tires. '47 GMC 1 ton w/ 302, NP-540, 4wd, full width Blazer front axle. '54 GMC 630 w/ 503 gasser, 5 speed, ex fire truck, shortened WB 4', install 8' bed. '55 GMC 370 w/270, 420 4 speed, grain, dump bed truck from ND. Works OK.
