4x4 Axle Width? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BigSix · 07-13-2014, 02:24 PM

Does anyone have an accurate wheel mounting surface to wheel mounting surface measurement for the 4x4 trucks? Specifically 3/4 ton would be amazing but 1/2 ton should be the same. I only ask because searching is bringing up different numbers. I'd like to see if there is a chance of me swapping axles with anything from another truck.

Is there a front Dana 60 that bolts in?

if chevy or GMC had them in their 3/4 or one tons up to 87 they should be the same width at the spring mounting

The WMS to WMS on a Eaton HO52 should be 65.5". The width on a '73-'87 10.5" 14 bolt in C/K20 will be about 66.875". The typical '63-'70 12 bolt in a C/K10 will be 62". The typical '71-'87 C/K10 differential will be 63.5". Some of the '63-'72 C/K20's did come with Dana 60's in the rear. I would have to check on the WMS to WMS on one of those.
