It is specifically designed for the Gamma and Gamma II engine families (G4FA, G4FC, G4FD, G4FG) found in most Hyundai and Kia subcompact and compact vehicles.
What are the signs of a leaking rear main seal?
Common symptoms include oil dripping from the inspection plate between the engine and transmission, oil spots on the driveway, and a drop in oil levels without visible upper-engine leaks.
Is this component a direct replacement for the original part?

Absolutely. This part is manufactured to meet exact OE specifications for inner diameter, outer diameter, and width, ensuring a professional, leak-proof press-fit.
