The big rear axle from the factory was the 9.25. Small axle was the 8.25.
Rumor of some 5 lug Dana 60's used in 70s vintage big block trucks but I've never seen one. Most Dana 60 are 8 lug.
Unless you're making lots of power the 9.25 should be adequate, I'd upgrade to a crush sleeve eliminator.

i think the 5 lug dana 60 were used only by IH------94-01 mexican ramchargers use a heavy duty dana 44---at about 120k my 2000 mexican spit out the dana 44--i upgraded to a 2002 9.25 disc brake from a 1500 truck.....bob

IH, Ford and Jeep used them in late 60's and early 70's heavy halfton.
An 8 ug 60 rear can be bolted in, but you'd need different wheels front and back unless you swapped the front to 8 lug as well

The loads on the "C" clip axles at the C clip probably isn't very high under normal conditions. If you are circle tack racing, or doing hard corners on blacktop, constantly, the C clip may be a weak point, at some point, maybe.
Probably the weakest point on a 9 1/4 is the axle bearings running on the axle surface, or the crush sleeve at the pinion gear collapsing and allowing the drive shaft flange to loosen up and drop the pinion back into the housing. Those are the two most frequent failures I've seen on Mopar 9 1/4 rear ends, and for as many of these rear ends as I've seen, it probably wasn't much of an issue.
I would not be concerned with a 9 1/4 under a Ramcharger with a big block, unless drag racing was the main intended purpose. Regardless of the opinion of many on this board, a 9 1/4 is a tough rear end. Gene

Dono, OK, so I ASSUMED the guy wasn't going to enter his truck in a demo derby, or I would have included that with the disclaimer of circle track racing, and consistently doing hard cornering on blacktop.
Thanks for the tip on demo derbying a 9 1/4 though. Should I decide to enter one with a 9 1/4, I will add the extra step to build up the ends of the C clips so they won't fall out. How many times to they take a direct hit before they fall out anyway?
Under normal driving conditions, and a few trips to the drag strip from time to time, YES, I see no reason a 9 1/4 shouldn't be under that Ramcharger. Gene

i have a narrowed 9.25 to A body width with 8.75 axle ends to eliminate the C clip---you have to buy a custom axles for it-----drag race guys have to use a C clip elimination kit and the ford 9 inch axle end is the most common one to use--(-you can use 8.75 axle ends also like i did)----my axle runs a 2.7 posi that i first envisioned as a bonneville axle for my 64---it now is under my 50 hudson as a cruiser set up......

Mexico received D60 rears in 5lug. Otherwise trucks only had 8lug D60s for Dodge.
