Secure Your Engine with the New Genuine Nissan Engine Rear Main Oil Seal Retainer. This factory RB26/25/20 retainer, found on all GTR models including N1 variants, is a critical component for maintaining a proper seal. Made from cast aluminum, this unit securely holds the rear main oil seal and reinforces its alignment against the engine block. As these retainers are obsolete and increasingly difficult to find, Terra Firma is proud to offer this genuine Nissan part. Whether you're rebuilding your engine or addressing a leaky rear main seal, replacing the retainer is essential to ensure the proper seal alignment between your crankshaft and block.
