MII or S10 frame swap for AD truck? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Orange52 · 07-09-2009, 04:14 PM

I can't make up my mind. Keep going back and forth trying to decide which way is the better way to go. Each has its pro's and con's. I have both. Ie I have my original frame with an MII crossmember installed (then slightly butchered by me, but nothing a competent fabricator couldn't fix. ie not me), I also have a std cab longbed S10 frame with v8 installed and cab mounts created using plans from Jeff51.

I want a truck that I can reliably drive across the country if I want to. I've read some bad things about MII's tearing the I bolts through the upper A arm mounts, and the fact that special bearings are needed to run the GM rotors isn't something I like.

On the other hand, I don't like the idea of running spacers in the front if I go with the S10 frame.

I'd have this thing done by now if I could just make a decision and stick with it!

Ok, throw your opinions my way! Which is better?

The spacers for the S-10 are perfectly fine if your not planning on taking it off road. They will hold up. You could also get a deeper back space on your wheels. Someone correct me if I'm wrong though.

I've done the s10 swap. I like the s10 swap as far being really low and still being able to turn. I'm not running spacers on mine. It works for me.
Later,
Josh

i'm a fan of the m2. i prefer to use the original frame. i haven't done a s10 swap so i can't say it's easy or hard. but i did the m2 wasn't that hard it was everything else that was hard. and yes get a pro do do your welding. suspension installations are not the place to practice your welding...

Did the S10 swap myself and same issues with the spacers... currently running 2 1/2" ones just for layup, but will be mocking up and building a tubular set, probably from chromoly tubing in the future.

Will post them when I do.

Cheers,
Ted.

i don't have any spacers on the front of mine. i don't plan on putting any on. without spacers with stock s10 wheels it gives you a tucked look which i like. i am also running the stock 2wd rear axle with 10 inch wide mags and the backspaceing on the is the same as the stock wheels so it brings the back wheels out to where they need to be. take a look at my build pics and you'll see. the only thing is when i get my box put together i will need a little mini tub in it no big deal.

For me it was the availibility of the s10 frame and other major components that I already had on hand. I have 15 x 8 cragars with a 2 1/2 back spacing. They fill out the wheel well nicely. I won't run spacers at all. If reliability is what you are going for, the s10 is about as reliable as you are going to find. Not to mention parts are in every town you will roll through. How'd the mounts work. I hope they are working for others and not just me.

Thanks,
Jeff

Jeff, I've got the front cab mounts temporarily bolted in place, I think they'll work great. Now I just need to decide if that's the best way for me to go.
