Franklin Performance billet aluminum half-moon seals replace the stock rubber seals used in the back of the Nissan RB and Nissan VG30 series cylinder heads.
The billet half moon seals eliminate exhaust valve cover oil leaks in this area, and are reusable.
The 6061-T6 aluminum used to manufacture will not shrink with exposure to heat and oil, which can be a problem with the stock rubber seals.
Suitable for:
Nissan RB20DE
Nissan RB20DET
Nissan RB25DE
Nissan RB25DET
Nissan RB26DETT
Nissan VG30DE
Nissan VG30DETT
When installing the seals, liberally apply silicone sealant to all sealing faces.
Sold as a pair.
