My new XJ has spacers on the front coils and sits level. How do I determine if the control arms are stock or longer after market arms and if the leaf spring shackles are stock? I need to know so I can order stock control arms and shackles when I remove the spacers and replace the leaf springs and coils. (Returning her to stock height.) Thanks!

Could you post us a few pics and we can tell just by looking at them.

For the control arms, here are numbers that are posted around the interweb

Lift---Lower Control Arms/Upper Control Arms
-------Decimal-Fraction-Decimal-Fraction
Stock 15.75 15 ¾ 15.00 15

Not sure of the validity. Coudn't testify in a court of law to it.

Thanks y'all! I decided to replace coils, shackles, and leafs when I remove the spacers. Control arms to be determined...

Check out Core4X4 adjustables when you make the switch! Quality stuff. Just get help, or a come-along when you do the swap

Oooh, those are pretty! Not sure why I would need adjustables though if I'm returning to stock...?
