Genuine OEM Nissan RB Rear Crankshaft Oil Seal – 12279-5L310

Genuine OEM Nissan rear crankshaft oil seal (rear main seal) to suit a wide range of RB-series engines, including the legendary RB26DETT.

The rear main seal prevents engine oil from leaking where the crankshaft exits the rear of the engine and mates to the flywheel. Over time the original seal can harden and wear, resulting in oil leaks between the engine and gearbox. As replacing this seal requires gearbox removal, it is highly recommended to fit a new genuine Nissan seal whenever the clutch or flywheel is being replaced. Genuine Nissan seals provide the correct fit, material and long-term reliability.

Ideal for clutch replacements, engine rebuilds and preventative maintenance.
