What UCA will work with my 6" readylift ??

Believe my upper ball joints are getting bad, looking to replace the stock uca with a better one... not sure which will work for my lift setup. Anyone able to help.

 

Ready lift has their own upper control arms. You might want to check with them. They have outstanding customer service.

did you ever get anything lined up for this? i think i'm needing new UCA's soon. their 6" kits are designed to work with OEM UCA's. i sent them an email earlier and they replied saying if the aftermarket UCA is at factory spec then yea, but better off utilizing an OEM part. let me know if/what you did.
