FAQ

Does this kit include everything at the rear cover?
Yes — rear main seal, wear sleeve, and rear cover gasket for a complete reseal.

Is the seal rubber or PTFE?
PTFE (Teflon) one-piece design for excellent heat and wear resistance.

Will this fit E-Series vans?
Often yes for 2004–2010 6.0L vans, but verify by VIN before ordering.

Any installation tips?
Clean the crank flange and cover bore, use the proper installer to avoid lip damage, and allow PTFE to “set” per service manual guidance before startup.
