So I recently got the swaybar set from HPI for my 5T conversion to help keep the longitudal roll down and I got a nice surprise. Included in the set is capture ends for the upper suspension arm pins. Should really be standard on all Savages!
You can get them by obviously ordering the swaybar set, or ordering the spur tree #102520 (if you can find it) and some Z567 screws to attach them.
i posted about this here. Didn't know you could buy the captures separately though, that's helpfull.
What would be even better would be if there was just a fix for the bumper supports to stop them being able to turn. Maybe notching them. I haven't had any issues since i zip tied mine. If they didn't rotate the new captures wouldn't be required.
