Are any of these interchangeable? I know the c5 = c5z (they are the same arms).

C6 has a different rear spring arrangement (like the front), I do know that.

froggy47

Thanks, yes, know that.

Anyone?

The poly bushing kits for the C6Z are different than the C6/C5/C5Z. It maybe just how the rear uppers bolt to the frame on aluminum frame C6Z?

Obviously the rear LCAs are different on C5 vs C6.
Same for rear upper control ares for C6Z and C5 (and steel frame C6).
Would be curious to know if anyone has info re C6 steel frame rear upper vs C5 and front UCA and LCA vs C5.

So a big no on the rears, as I suspected.

How about fronts? Upper? Lower? Someone must have owned both c5 and c6/c6z. Ever look at the ca's?

Here is what I have found so far

Front Upper control arms are interchangeable between C5 and C6 (also considerable cheaper)
Uprights are interchangeable between C5 and C6 (09 and later C6 uprights are much stronger than earlier ones)
I BELIEVE front lower control arms are interchangeable

I wonder if the rear upper C6z control arms will work on a steel frame car if you dont use the dogbones - ie if you remove the oem bushings and use an aftermarket bushings kit for a steel frame car...
