Nissan Stagea C34 RS-FOUR Oil Crankshaft Rear Seal NOK, Early Series 1 RB25DET

The Nissan Stagea C34 RS-FOUR oil crankshaft rear seal for early Series 1 RB25DET engines is a crucial component for preserving factory performance and long-term reliability. This genuine Nissan part, manufactured by NOK, is designed to maintain the proper seal at the rear of the crankshaft, preventing oil leaks that can compromise both engine function and drivetrain components. Specifically engineered for the RB25DET in production from September 1996 through June 1997, this seal ensures the correct fitment and durability expected from OEM parts.

Over time, rear crankshaft seals are subjected to constant rotational forces, high temperatures, and exposure to oil, which can cause them to wear or harden. A failing seal can lead to oil leakage, clutch contamination, and costly repairs if left unaddressed. Using a genuine Nissan NOK seal provides confidence in performance, as it restores the original specifications and maintains the integrity of the RB25DET engine in your Stagea RS-FOUR.

As original components for the Stagea C34 become increasingly difficult to source, having access to authentic OEM replacements is essential for proper maintenance and restoration. Terra Firma Automotive specializes in supplying hard-to-find factory Nissan parts, ensuring owners of the C34 RS-FOUR can keep their vehicles performing as intended. By replacing worn seals with genuine units, you not only prevent potential failures but also preserve the legacy and value of your Stagea.
