Correct Lift Procedures?

I think the Spring Over Axle (SOA) is a great lift for a CJ or YJ! 8" is an exaggeration though unless lift springs are used. More like 5-6" with stock springs. Spring wrap can be a problem depending on springs used and available torque. My stock CJ springs with an add-a-leaf don't have any wrap. I see Bill left a good link to get started.

What you found is called a Spring Over. A spring over is a common way to lift a leaf-sprung vehicle, and in some cases the factory fitment of the springs is a spring over - there are no CJs with a spring over from the factory, but I am pretty sure there are other models that come with spring overs stock.

In any case, the "lift" is measured by the springs themselves, so you might say, "I have a 2.5" lift with a spring over." Since the spring over results in about 3.5 inches, you have a total lift of 6". If you only had a spring over, you would lift your Jeep about 3.5". Get it?

The Jeep you found sounds like it has 4" springs on top of the spring over, giving you what you estimate at 8" of lift.

Waggys came with one axle spring over, and one spring under.

XJ/MJ rear is also spring-over stock.

That's what was stuck in my head when I suggested there were models that came as spring overs. The Wagoneers had a spring over on the back, but not the front. < he said, not noticing that Dave already knew that>

what Dave doesn't know is *why* they did that ?!?

And Greg wants to know how you lift one, do spring over in front and 3" blocks in back? Freind just bought a 75 cherokee cheif, needs lifting.

Yup, that's the way. You can get anti wrap blocks too. These are longer or have a longer piece attached to keep the torque from twisting the springs.

Longer bump stops and shocks are also needed to do it right.

This just gets you clearance, it does not help with articulation as the stock axle travel is still there.
