Are those the ones with the plastic reinforcement? Have you test fitted these by chance, because I found them slightly larger (OD) than the stock ones... which makes them a bitch to fit. You should get some Mil-Spec shaft seals as another option, like OEM (metal reinforcement) but the inner seal is much better.

These are constructed just like a normal seal. It's the same seal that all of the DSM vendors sell. I'll put some in a TB here at the shop later today. Lord knows I need to rebuild a TB for Em's stealth anyways

They look like the ones MachV sells, except yours are cheaper... I found them very difficult to install without ruining the outer casing (it sort of "shaves" a little bit of plastic off because it is ever so slightly larger than the bore on the TB). The ones made by Mil-Spec look just like OEM except the inner seal is more substantial, and press in perfectly.

Thanks for the insight. I sent them an email. So we'll see where that takes us
