swapping in WJ LCAs

If you are just swapping stock WJ LCAs in place of stock XJ LCAs and all the bushings are in decent shape, you don't need to have it realigned. The center to center distance between the XJ and WJ arms is the same so there's not change in steering geometry.
 
Some people seem to think you need an alignment if you just crawl underneath and look at the front suspension. Don't worry about it unless you notice anything funny.
 
Dumb question, but why swap in WJ LCAs?
 
Thank you :)

One problem with the WJ LCAs is because they are taller they will come in contact with the lower shock mount when the suspension is drooping. It's not a problem with little or no lift but once you get up to 4" or so it limits articulation. Of course you can get some of it back by trimming the shock mounts.
