Upper Control Arm Shaft - What to torque to?
I have a set of SpeedTech UCAs for my 68 Camaro.
The instructions did not mention a torque spec for the UCA cross shaft bolts... what should I torque them too?

I was just talking to Mark at SC&C about a similar topic today. He recommended 60 ft/lbs for the 7/16 grade 8 bolts I'll be using on my SPC upper control arms, would be closer to 80 ft/lbs if you were using 1/2 inch grade 8 bolts.

I emailed SpeedTech and they said adjust them like a wheel bearing, snug it up and insert the cotter pin.

I think the responses differ from the question here. eville, you are talking about the specs for the ends of the cross shaft correct? Where the UCA bushings are? Then yes, it is like a wheel bearing. The shaft to frame bolts require a torque spec as noted above.

Do you still believe in all the things that you stood by before? Are you out there on the front lines, or at home keeping score?
Do you care to be the layer of the bricks that seal your fate? Would you rather be the architect of what we might create?

Yes, they are actually nuts, at the ends of the cross shafts next to the CA bushings.

Yeah, my GWs with Del-a-lum are the same way. You have the right info now.
