I am not sure either. Maybe in time NR with come out with an kit for the uppers. I bought the synergy UCA kit and NR kit when I did my lift and swaped out trackbars and control arms. Piece of mine for down the road

Just figured I would bring this back up and ask the same question again since it wasn't really answered.
Sooooooooo, the Northridge bolt kit is just for the lower control arms and track bars. Any reason not to replace the upper's bolts with grade 8 9/16 units too?

The bolts are well worth the investment though.

Synergy has a kit. I can't imagine you'd get them in for the front of the rear uppers. I hate taking those out. Super long tab on those. The load on the front uppers isn't as much as the other arms and they're smaller bolts. I guess the logic is partly ease of replacement for the lowers and track bars.

Thanks for the reply, fellow Michigander.
I have the NR bolt kit already. Just will be installing my RK kit soon, and wondering if I should get them for the uppers while Im there or not bother.
