I've built many trucks and used heims for control arms with no issue, sure if all you do is drive it to the mall there not the best choice, if they made rebuildable joints in a more narrow size I would have used those... But they don't, and I destroyed man a fres crappy poly bushings so I decided to make my own at a fraction of the cost. I can live with a couple creeks and pops.
These are rebuildable, not sure if they would work with stock brackets or not.
