I walked into my off road shop today and said "I gave my truck a nick-name - Ilene" as in I lean to one side. Before I could say anything more, the guy behind the desk said "Oh. Your JK is sagging in the right rear, right?" WTF!

He said just about every JK with a lift ends up sagging to the right rear, regardless of lift kit installed or if stock. He speculated that it has to do with the fact that 1) the gas tank is on that side, and 2) the rear differential torque is forcing that side down more. The fact he knew what I was talking about with an obscure "Ilene" reference before I even completed my sentence leads me to believe there is a common problem with the JK sagging in the right rear.

OK JK-Forum members! Let's hear if you have experienced this spring sag too! What can be done about it? Different spring rates from right to left? Seems extreme. Anyone else having the same issue?

BTW - using after market Black Diamond springs and the right rear sag is about 1".

 

How many miles are on the lift? I just installed mine but I heard it was an issue with the TJ for the same reason.

 

Was the ones on your TJ before or after Superlift acquired Black Diamond from Warn? I'm pretty sure the current Black Diamond Springs are equivalent to Superlift.
