Ok.. Trying to figure out the best way to add more positive caster.. Is it upper or lower? ( upper being a bit cheaper) and how is the install on theses ... Anybody do one and can give some tips.. All help is thanked!!

 

Pretty sure the way to do it is lower fronts and upper rears for best results.

I'm sure someone more knowledgeable will extrapolate, but my understanding is that there is far more adjustment with front lowers than with front uppers, and this method also allows for correct geometry at all ranges of articulation and flex.

 

You add longer arms for the bottom or shorter for the tops to add castor. I prefer the longer lower arms as it also recenters the axle in the wheel well and they tend to take more abuse when offroad since the factory arms are stamped. The aftermarket are much stronger.

 

There is some information in the Suspension Questions FAQ and specifics on the installtion in the Basic Do-it-Yourself Jeep JK Wrangler Front End Alignment write-up.
