Default solid axle swap on my S10 blazer

I would like to convert my Blazer from IFS to a solid axle. if any one here has done it I would like to know exactly what is involved and how costly the whole project will be.

If it is done right, it costs quite a bit.

I half assed some stuff on mine and I am still not done yet. I think I have somewhere near $750ish into mine.

I ended up cutting out my whole front end with a torch and scrapping it. Made a new front crossmember, cut out old one, I have to modify my Y-pipe to make room for a front driveshaft, brackets for arms, panhard bar, shorten steering link, shorten panhard bar, steering box from an Astro, turn rear springs around, replace all the rear leaf bushings, make front coil buckets, make shock mounts, make shackles, brakework, make my new driveshafts and take them somewhere to get them balanced. I know I am missing a few things for sure.

It takes a lot man, there are endless ways to do something like that too.

Search around. There is a lot of stuff in this site about that stuff. Check out www.zr2usa.com and www.s10forum.com also. Lots of info, just need to search.

I did research for almost a year before I started mine, and now I don't even know if I did enough.

Something I forgot to add...

It is easier for people to help you if you know what you want out of your vehicle once the project is done. Like if you want a low center of gravity, or jacked way the hell in the air, tire size, for mud, rocks, dunes, whatever.

CAGE off road makes a bolt in sas kit to put a ford axle in the front with radius arms and coils. Not sure what years they make it for tho.

I know this is a bit late for this thread, but here is a link to my straight axle swap I did on my 96 Jimmy.

http://www.griztekusa.com/JimmyProject.html

Feel free to ask any questions. If you have fab skills, grinder , sawzall, welder, and maybe a chop saw you can do this all for less than $1000. I still own this truck 5 years later and have had no problems. To this date I have put on over 60K miles on it since the swap. Dont' let anyone tell you it must be a hack job either. Many people have been very impressed with the complete package and are amazed it looks and functions like it does and I didn't spend an arm and a leg to do it.

old fords 78 79 so on came with coil spring and trailing arms, if you can find a set of 44 hp and 9" on the truck, you can cut off all the buckets and brackets and wield them on the s-10 quick and ez, i sold three sets of them this year and every one had great results. the one is a s-10 running around tc right now the guy uses it for a dd (black newer style and squats in the rear a bit look REAL GOOD pre runner style)

call the dealer with the VIN#
or pull the cover and count the teeth
or count driveshaft versus tire rotations

Bet ya a beer it's 3:42 which you wont find in a jeep.If you get lucky it will be 3:73 a common jeep gear also. It could also be 3:23,or 4:10 if it was ordered.
Fyi get a 8.5 ten bolt for the rear out of a zr2 .They have disc brakes,posi,and are much stronger then your 7.5.They bolt in,and most have 3:73. I see them at lkq all the time for less then $200.

The G80 in the ZR2s is garbage. If you get one, you should throw it out and replace it with something better.
