Default Converting from IFS to Leaf spring

Ok...Im still new to this whole tech thing, but I just have a few questions about converting a 92 chevy k5 blazer, with IFS to have leaf springs in both the front and rear. I have not yet made up my decision about doing this lift.

I want to get other people's input before I do anything major...So, has anyone done this sorta thing? and are there any pro's/cons to doing this? What will I need exactly to make this happen? I ask this because I want this truck to be like 8 or more inches, and from what I've been finding, suspension lifts only go up to 6"...

Any thoughts would be greatly appreciated...

Again, Im a noob at this, so please, go easy :-D

Thanks,

John

A solid axle swap is a big time task. I'm not saying don't do it because it is awesome when done , it just requires fab work and precise measurements so that you don't booty fab the truck and down the road it falls apart and kills someone.

Lots of people have done the swap before. it depends if your rig is going to get beat on repeatedly off road than a SAS is a good idea to replace the weak IFS but if it is just a street queen I'd save your time and get a suspension lift and a body lift to get the desired height.

This link here will provide you with tons of information so you can make a good well thought out decision before you cut your rig up. http://www.fullsizechevy.com/forums/...sion-tech.html

Good luck !!

Off road direct makes a bolt on swap kit too, you can also buy their parts individually to save money.

if it is just for looks you can get away with a 6" suspension lift and a 3" body lift and if thats not big enough yet you can trun your torsion bars up and get a total of about 11" of lift and still be IFS. if your actually going to off road it you almost need to do a SAS because the front cv shafts and differential are way too weak to handle anything over 35" tires(im assuming you want over 35's because you want atleast 8" lift). i ran the IFS in my 1990 half ton gmc for about 6 months and broke 5 cv shafts(had lots of spares..lol) until i decided that i needed to do a SAS if i ever wanted to do more than 5 minutes of wheeling.

in the end it all comes down to what you are going to use it for.

also remember that once you lift it and throw some big tires on it you will need to regear it and if you do a SAS you can normally buy axles with the gears that you want for less than it costs to regear the axles that you have.
