I installed a 2.5" spacer lift ( Yes i understand its the worse way to lift a KJ) but any how the drivers side clevis is rubbing the CV boot and the passenger side has like 2 inches or so of clearance. Can anybody tell me how to fix this or what could be causing it?

I can't help, but those who can will need to know if your rig is a crd or gasser, what year it is, mileage and whether or not the rest of the suspension is stock. If you provide, I'm sure someone will have some insight.
Good luck!

Is it rubbing when all 4 wheels are on the ground?
If so, you have too much lift or your spacer is pushing the clevis down too far.

2.5 lift shouldn't cause any cv boot rubbing while all 4 wheels are on the ground.

pictures would help

I discovered the CV boots can be different between OE and aftermarket. The OE ones are stiffer and seem to take up more space. It always seems I have to take more of the Jeep apart to remove an OE shaft.

How about shimming your engine cradle down? 1/4" is easy and might be all you need for clearance.

Exactly how easy is it to drop the cradle 1/4 inch?
What do you use for shims?

Thanks for the response and i will try to get some this evening. Im still in the process of finishing it and havent put it on the ground yet but with a jack under the LCA and jacking it to the point that the vehicle is rising it was still rubbing, the spacers measure a little less than 2 inches.
