Are these blue orings cheaper than the OEM orange ones? Are they made in china or something? Not all orings are made of the same material. I wouldn't take a chance if it were me.

i sold a guy the real parts and he returned then to me because he could get chines parts for a fraction of the cost. You will never see me taking a short cut on some orings that could fail on my $20,000 motor let alone a customers rig.


AMEN

I have a hard time keeping my engine together with all the good stuff. No way I would risk cheaping out.

Just when you think you can trust your parts source. Looks like I need to find a new one. Yay

You got one!......Tony Burkhard,,,,Tony is the duramax engine builder that uses the good parts. And there are other engine builders out there as well that use good parts the list is long and proven.
Look at how good Tony's truck runs!....

WHY would anybody want to deal with someone who does NOT race or pull or even have anything that makes the top five or top eight,,,,but sells parts?
