Arrow What 3/4 ton Axle Fits 67-72 1/2 ton 4x4s?

Hey guys....... New to this forum but not new to forums in general looks like a great site

Anyways I'm in the process of buying another 67-72 SWB 4x4 (owned a few including k-5s) and would like to know which year axles off a 3/4 ton Chevy i.e. only 67-72 or other years & models etc. will be a direct bolt in for a 67-72 1/2 ton SWB 4x4 truck. BTW I tried searching the forum for my answer with no luck before posting this thanks in advance for your help fellas.

I know the dana 44 and 10 bolt front from 73-87 is a direct bolt in provided you use the later u bolts and clamps. Then you get disc brakes. Dont know of a bolt in rear as the spring pads need to be moved and shock mounts as well to run the later 14 bolt.

Welcome aboard from another swb 4x4 collector. I believe, like stated, both the dana 44 and 10 bolt will bolt in fine up front. The only rear you could use without moving the spring perches is a Cab and Chassis rear end. Trevor

The widths are all the same on the 67-72 1/2 ton axles and the 73-87 3/4 ton axles then?

for a rear end, any 1ton 73-87 will bolt in...all other later rear ends require moving perches....which isnt that big of a deal

I just put a 1995 14 bolt dually from a cab and chassis in mine and it was a direct bolt in. The e-brake cables are different length and the shock mounts are different. That's ok for me since i will use the 95 style shocks.

Yes, the widths are fine. The ONLY rear axle though that will not require modifications is a 1 ton Cab and Chassi rear end. Everything else will requires the shocks mounts to be moved and possibly spring perches as well. Trevor
