rear main seal

[odee]

working on putting clutch in my 86 gmc with the cummins swap. I have the fel pro rear seal set already. Is the factory cummins seal seal better to go with, I just want to drop the tranny this one time. thanks

yes

I am 1 year and nearly 40k miles since I installed my Felpro. Had a well known shop say that unless it is a head gasket, they pretty much use Felpro.

I've installed a bunch of felpro and I've had no problems....real problems. Install the thing with the lip and crank surface dry.
