1 Ton front crossmember in 1/2 ton?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

spudz · 01-05-2011, 03:11 PM

OK I am gettin a lwb square on trade. Runs good, th350 needs a rebuild etc. Base model truck. I want to put 1 ton suspension under it. Is it as simple as unbolt a 1 ton crossmember and bolt it under the 1/2 ton? I know the 1/2 ton frames are thinner in gauge and shorter in height. How about the rear? Are the springs different lengths? I seen a thread about putting a 1 ton front end under a 1/2 ton not too long ago. I cant find it for hell now.

the front will swap over no problem. dont know about the rear

Yes front susp. will bolt right up..you can even put the ton front susp..under a 67-72 frame..bolts right up to them..less 2 bolts..

I have a front ton susp out of a 2wd 87 crew cab dually here..$100..Only thing is the calipers are gone..rotors and everything else is there..

I havent gotten the truck home yet. Hopefully before the weekend and I will take pics then!

If you use a 3/4 ton 14bolt instead of a 1 ton 14 bolt then the rear axle should just bolt right up. I believe the one tons have the spring perches closer to the frame (I know the D70HD dually axle I have has the springs mounted closer to the frame, i know your not going dually, im just saying).

So really if you get the whole 1 ton front suspension and a 3/4 ton 14 bolt for the rear it should just bolt on!

Dru · 01-06-2011, 06:03 AM

hehe.

Im guessing it was my thread that was being referred to, my 1/2 ton frame was actually a 1/2 inch taller in the crossmember section than the 1 ton frame, so the brackets that set on the inside of the frame weren't usable, but hey I get to rip it all out again anyhow after discovering a bent frame.

Hope your swap goes well spudz, post some pics too please, I haven't got to the rear of mine yet, but will have to when I put a new 1 ton frame under it.

spudz · 01-06-2011, 12:52 PM

Ok here ya go, I had my buddy who is bringing me the truck tonight snap a pic. He has it loaded up and ready to go. I am going to ATEMPT to rebuild this transmission myself. Ive never been into a th350. BUT cant be any harder then 700/4l60s.

YEAH! it was you. Not sure what you mean by the inside brackets.. Could you explain what you had to do to overcome it?

thats a nice truck

Both front and rear will work if its a SRW. Remember Blazer/4x4 guys swap 1 tons all the time.

By inside brackets he means the ones the go from the frame to the crossmember. 1 tons have taller frame rails.
