MAPerformance Rear Main Seal Housing 4 Cylinder Ford | Mazda 2013-2021
$174.99
One of the most common issues we have seen when it comes to the 4 Cylinder Ecoboost engine has been the leaking rear main seal. Stock and modified motors seem to all fall to the same fate of a warped or worn seal. We have replaced the flimsy stamped factory piece that has a non-replaceable hard seal, with a 6061 Aluminum seal housing, and replaceable seal. Not only will this prevent the oil leaks, but it also offers the ability to service it with replaceable parts, and stiffens the rear of the block.

  • 1- MAP Billet Rear main seal housing with rear main seal installed
  • 2- 110 Viton O-rings
  • 4- M6x16 Allen bolts
  • 2- M6x1.0x18 Allen bolts
