What rear end is this? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

PO says its the original rear but the bolt pattern looks off from a GM 10 Bolt. Its under my 67 C20

That's the correct Eaton HO52 for 3/4 tons. Its probably the stock rearend. That's a WHOLE lot more rearend than a regular 10 bolt. They are real strong, but gearsets are limited.

theoneandonly · 06-22-2008, 09:45 PM

did it come with 4.10s? thats what the po said it had

Longhorn Man · 06-22-2008, 09:48 PM

4.10 was standard in small block/automatic 3/4 ton trucks, may have been witht he 4 sped trucks, and avalible in other combos... so yeah, it was avalible in the eaton/corperate HO52 rear end.

Most likely, that was the standard gearset, but they could also be had with 4.56, 5.14, and 5.38's. 4.10's are the highest gearset it could have had from the factory, and it is the most common in 3/4 T's.

Cool thanks I was lost there for a min.

never heard of the 5.38, not in this generation of truck.
The standard base model C/20 gear was 4.56

there was a 5.83, perhaps thats what he means? I think that was only available in the p chassis.

looks like the same rearend I pulled from a 60 chevy 3/4 ton. 4:10 rear end.

Is there a list of parts from a 14 Bolt will interchange with these rear ends? I need to know before I just swap a 14 Bolt into mine.
