Oil leaks? Not on our watch.
Fuji Racing’s billet half moon seals are the go-to solution for sealing off rocker covers on Subaru EJ engines—without relying on brittle, failure-prone plastic plugs.
CNC-machined from T6061 billet alloy, these seals are precision-fit replacements for the OEM rubber or plastic units that often fail after heat cycling or when changing rocker cover gaskets. If you're chasing long-term reliability and want a fix that holds under pressure, this is it.
💪 Billet T6061 alloy – Won’t crack, deform, or deteriorate
🧰 Direct replacement for OEM part numbers 11051AA070 / 11051AA040
🔁 Works with RCM2728, RCM2616, IAG-ENG-2000 equivalents

📦 Kit includes: 4x billet seals (enough for both heads)
If you’re unsure about compatibility, flick us your chassis number—we’ll confirm it for you.
