well because it would have been autohaus Arizona that botched the order not the manufacturer of the rings. I suppose i could call autohaus AZ and see if they did in fact screw the order and if they say they are for a diesel i could then call Grant and ask them? but if one were better than the other why would they sell them at the same price?
The fact that total seal uses a three piece oil ring makes me want to find the opinion of you guys.
In my opinion total seal seems to be at the top of the pack for rings... and if they use a 3 piece system i was thinking there may be something superior to that design no?
Do those other rings fit around your pistons? It looks like you may have received a gasser set. Here's what I was [incorrectly] sent:

They are sort of like that but that part of the ring is thinner, it fits in sideways not flat like that and there aren't coloured tabs on it. they just overlap and kind of lock together...
Ed, slightly off the topic.. Did you get the entire pistons from you know who, or just rings?? I bought a set of his pistons, which seem decent.. But now you've got me debating whether to use the rings that came with, or buy another set...
I am using my OEM pistons i believe.
