they are perfectly interchangeable to the original ones, and they can be fitted both on the crankshaft and on the CVT's primary gear. they are made of FKM (fluorocarbon rubber) to better resist to the highest termic stress; the seal lip is made of PTFE (polytetrafluoroethylene); this feature makes them a lot more durable than the standard original ones, giving them a smaller friction coefficient thus granting less heat dispersions caused by the friction and at the same time maintaining lower temperatures. these oils seals have been studied with racing engines but equally they perfectly fit on the standard engines that haven't been tuned-up. more power is produced from the engine as the friction reduction allows it to reach higher revolutions ranges.

Put one on my stator side on my Targa. Will put the other one I bought on the tranny side when I have to open it up again.
So far so good.
