I drove my '52 28 miles home from storage a couple weeks ago and already know I want a higher gear ratio than the 6.13. I got it all the way up to 48 mph and the engine sounded like it was ready to come apart. I would like to get into a newer axle with standard 10 bolt budd wheels and hydraulic brakes. A ratio in the high 4's to low 5's would be good. Has anyone done this swap to recommend an axle that will match the spring width ?

I did read about some people swapping in a newer 5 speed overdrive trans but that doesn't get me away from the hard to find wheels and tires.
That could still be an option, depending on what I find for gear ratios in a newer axle.

There are previous comments in this subject; D 70 and 80 rear axles come w/ that bolt pattern(10 on 7.25), up to 3.56 and even 3.3 ratios w/ disc brakes. The hub is slightly larger, bore out wheels and cover plates if you have them, can use your 20" wheels; or can use 19.5" wheels(common), look too small on the truck though, or 22.5(hard to find) from '50's farm trucks.


'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.

I'm looking for expereince with something from the 80's, like an IH axle with ball seat wheels. Would like to get away from the hard to find wheels and tires.
