Spring Over Axle

How much will this lift my yj? When I do this, Will I have to change out my driveshaft and get a longer one to accomodate for the lift? Do I need to use perches on my axles for the springs to sit?

It should net you somewhere around 5" of lift, but it will vary. you will need new spring perches welded on top of the axle for the springs to sit on. You can buy generic weld-on perches for around $10-15 a piece. You will most definitely need to change your driveshaft, get it lengthened at the vary least. But more realistically, you'll probably been a slip yoke eliminator (SYE) with a CV driveshaft to accomodiate the new steep angles.

Rob is right it will give you about 4.5 to 5.5 lift. I did mine and it was 5" you will need drop pitman arm, longer driveshaft, perches,longer brakelines, longer shockes, and a good welder. you can get a good write up on soa if you go to this location

you can also get there from the jeep project section in www.jeepyj.net
Good luck if you want a pic. of the finished product just e-mail me mine is a 90yj

I recently got my new Quadratec magazine which had a set of soa paerches that bolt on to the axles. Seems like easy way to do an soa for a novice jeeper. It says that it is 4.5" lift. It doesn't include anything else like shocks or drop pitman arm. This is the first time i've seen anything like this. I'm curious to see if it works well. The down side is it costs about $400.
