Z71 to 3/4 ton conversion. Anyone done it?

i have a great old truck 92 Z71 has a NV4500 trans and a 5.7 that runs great. My only hang up is the 10 bolt and weak suspension. I am not wanting to sas this truck. just thinking about buying a parts truck 2500 8 lug and swapping everything over. Anything that wont just bolt up. I know the cv shafts are different size so i will have to use the front IFS carrier and cvs, but does it bolt right in. I dont have one to check out so I am asking for the knowledge from this board for help. Thanks

I think you probably found that it's do-able, yes? I've seen it done, so I know it can be done, but the rate at which things can just be swapped without modification is unknown to me. That's all I got.

Its pretty straight forward, but I might just machine down the 14 center and make a new bolt pattern to fit my wheels like this guy did.

Why is the 10 bolt and weak suspension a hang up? Are you towing something or hauling something that is overloading the suspension and axles? Or are you just bored and looking for something to do?

Sounds like a lot of work to get a truck that has 2500 suspension and axles and is still tagged and weight rated as a 1500.

And then why would you want to upgrade the suspension and axles but modify them to keep the same wheels and light truck tires from the 1500.

Sounds to me like you need to find a 2500 with a blown engine or trans and swap the parts from the 1500 to a 2500.

just find a mini 14b semi floater from one of those 'HD' 1500s. It has the correct bolt pattern and is a direct swap.

while i dont think youll break a semi-float 1.5" shaft,i personally think the full floater is worth alot of piece of mind. if you have wheels youre attached to and want to stay 6 lug id covnert a FF to 6 lug before swapping in the SF axle.

a friend of mine runs a 6 lug 14 bolt in his half ton chevy. the WTF looks it gets from people that realize its a 14 bolt then that its 6 lug are priceless

i personally would swap a FF in the rear. if you dont mind being 8 lug id leave it that way,and upgrade the rear springs. id prolly SAS it,but in a tow rig the 3/4 ton IFS would prolly work fine.

the key here is no matter what you put into axle wise its still a half ton frame... now i will admit im not sure of the differences between the frames in the old c/k body trucks BUT there is more than axles and some heavier springs that make a truck 3/4 ton.... what are your plans for it towing wise? ive never had any issues out of any of my half ton chevies and i used to tow 20 plus foot boats on a daily basis with them, as far as half tons go they are the best ive ever used

My intention is to fix the weak link. I read on another thread where they used a FF14 adn machined down the bud to fit 1/2 ton wheels and drilled new bolt pattern in the drums adn flanges. I am not attached to my wheels, but i dont want 6 lug on the frotn and 8 on the rear. Still lookin at options. thansk for all teh useful replies so far

i dont blame you,but id prolly make the front 8 lug to match it. my friend did the 6 lug conversion because he had aluminum wheels he was attached to and they dont make them in 8 lug.

i dont know what the various weight ratings are on stock wheels,but seems you should be better off in a tow rig with 8 lugs. if the IFS dont bother you just swap in the 1 ton IFS. otherwise id SAS it-even if you just used a 10 bolt.

i was definately not suggesting you run 2 different lug patterns and carry 2 spares in your tow rig
