Crew Cab

[bigblock79]

ok i hhave a 79 k30 crew cab. i sold the dana 60. i have a suburban with good axels i want to use 1/2 ton runing gear so would u just cut the ton frame to make it a short bed and use a 1/2 ton back half or would use the burb front half and a 1/2 ton truck back half i can go either way the burb is rusty bad so i bought it for the running gear got good 350 t 400 tranny and 3:42 gears what will be the best way

[csa daddy]

either way will work but i imagine cutting the burb an a short bed truck an put it together

[bigblock79]

thats what i think i think the burb frame be plenty big enough and loose the big frame less whight

[ghettoluxury]

That is how Doug and I built the frame under his crew short dually and this is the abuse it gets put through.

[dropd80s]

I wouldn't do either, I would just shorten the one ton frame. That is the way i did mine and I can't imagine putting two different frames from different trucks together would be easier. Plus I think this way gives you the best looking and strongest end result. JMO.

[bigblock79]

well then u have to put spring perch on the 1/2 ton axel to make it match the crew cab springs i want to run 1/2 ton axels not 3/4 ton or 1 tons

[dropd80s]

or swap the hangers from the 1/2 ton frame. Again, not that hard to do. I figured if your up to the task of cutting and welding a frame, knocking out a few rivits or welding two spring perches wouldn't be something beyond your capabilities. Again, in my opinion its the better looking end result.

I'm in the prosses of doing this right now. Unless you are using a 1 ton dually the spring mounts ar the same. If it is a dually they put spring mounts narrower

[dropd80s]

This is not true, all one ton frames either dual or single rear wheel have narrower perches. I have had a 79 and 84 crew cab single wheel K30, both had narrow perches.

[Red1]

dropd80s is correct the 3/4 tons were wider. I had thought the donner truck I was using was 1 ton but in fact it is a 3/4 ton sorry for the confusion.

my crew cab is a dooly and i sold the dana 60 out of it and going to sell the duel wheel rear and i want all 1/2 ton rear out of my burb under it

Ok, then you're going to need to move the spring perches on the axle to a narrower width between them, so it matches the distance between the leaf spring center pins on your one ton. If you're up to cutting up a frame and welding it, this should be a simple task.

the way i see i got to cut a frame any way i go. So why not loose the lbs of a 8 inch frame and go with the burb fame cause i want a short box crew cab so i have to cut the one ton frame so why not loose all the lbs i can
