I have talked to people at PAC about springs being made in Michigan. Sources of wire can be from outside of the US, but I have not heard they source metal or wire from China or make them in China. Anything is possible, but to be fair to PAC Springs, saying they make them in China deserves some validation since it is seen as a negative. What is the source of the info?

These are now "made in China" and I have heard some complaints about durability and longevity with them. Are they the only option
now? Are they that bad? Used to use Isky tool room but had an availability issue last time. Bullet said that the COMP's are too much and could be causing harmonic issues.
FYI also ordering a different cam when I make the change. Im looking for some input with real word results if possible.
thanks in advance
