If you're looking at these over a cheaper set I'd say it's definitely worth it. Like other people have stated the O-ring is a little big but it makes a good seal. Also you can find replacement bushings for the pivot balls if they ever wear out. There are little threaded holes on the face of the carrier. Not sure what they are for but I plugged them for future use just in case.

These have the tight tolerances that take the mini revo to the next level. I replaced RPM steering knuckles because they were sloppy and kept popping off the pillow ball under stress. The trick with these hot racing ones is grease the o rings before installing the caps so it doesn't tear the o ring going into the threads.

Had factory knuckles then upgraded to RPM. then now broke down and bought the titanium pillow ball ends to complete the upgrade and love it. Remember not to over tighten the red screw and lubricate with white lighting wax.
