Terra Firma Automotive supplies genuine Nissan differential seals that maintain proper fluid retention and long-term reliability in your Z32 twin-turbo. This rear drive pinion oil seal is the exact OEM unit designed to seal the pinion shaft as it exits the R200 differential housing. Manufactured to Nissan’s strict specifications with high-quality rubber compounds and a reinforced metal core, it withstands the elevated temperatures, pressures, and torque loads produced by the VG30DETT engine while preventing gear oil leaks.
Twin-turbo Z32 differentials endure significant stress, and a failing pinion seal is a common issue that leads to oil loss, contamination of the driveshaft, and potential damage to the ring and pinion set. This authentic replacement restores a positive, leak-free seal that keeps the differential properly lubricated and protected. Its precise dimensions ensure a perfect fit on the pinion shaft and housing, delivering the same performance and durability as the factory-installed seal.
At Terra Firma Automotive, we are the trusted premium source for genuine OEM differential components that serious Z32 enthusiasts rely on. Whether you are rebuilding the rear differential on your high-horsepower twin-turbo, refreshing seals during a driveline service, or completing a thorough restoration on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this pinion oil seal helps maintain the integrity and performance of the drivetrain.
