Eager to hear your long term review on the Apex setup. Was initially hearing a lot of hype but have started hearing some issues around the star bolt locks and such. It could be poor install, who knows. I'd stay away from synergy stuff for track bars. I hear nothing but complaints about their joints failing constantly.
If you're having death wobble issues, I'd look into this frame side track bar mount from Thuren (
Link). This was a pretty consistent issue in my time with Jeeps, and every time I had death wobble, or heard of someone who did, and couldn't figure it out, installing a frame side track bar mount solved the issue.
I can't speak to if it's the same thing with dodge, but I'd assume it's similar since their suspension is functionally identical just larger. Basically the track bar angle, matched with the larger mass from aftermarket tires and wheels, causes the frame side track bar mount to deform in some slight way. With my jeeps it was often that the mounting hole would start to ovalize but you could not tell without taking the track bar out because the compression was still tight enough that you couldn't move it by hand.
Either way, I hope that you're new steering setup is solid. I really want to iron out what I'm gonna do when I eventually wreck my OEMs, but thus far nothing seems like the best option.
