Adjustable Upper Arms

I've got a quadratec gift certif. but I called them and they dont stock any adjustable uppers for XJ's

Anybody know if TJ/any other adjustable upper arms are compatible with XJ's?

Thanks!

Edit: I'll be at 5" lift when installing these adjustable arms.

yeah i got some daystar uppers that are written down as tj,xj,zy adjstabe uppers but not sure if quadratec stocks em - all tj and xj uppers i believe that are adjustable will work - especially for lifts under 6 inches above that you might need something longer - someone needs to confirm this though!
