BMW 545I Rear Main Seal - Victor Reinz - '04-'05 is a direct-fit rear crankshaft seal for 2004–2005 BMW 545i models. It replaces the factory rear main seal to restore reliable oil containment at the crankshaft rear housing.

Built by Victor Reinz to meet OE-style specifications, this rear main (crankshaft) seal uses a durable elastomer sealing lip and a tension spring to maintain consistent contact under typical engine conditions. It resists oil and heat degradation common in service environments and is intended for installers and enthusiasts performing crankshaft, flywheel, or transmission service. The part is engineered for fitment accuracy to minimize installation fuss; as with all rear main seals, proper installation technique and verification of mating surfaces are important for best results. Verify fitment with your vehicle VIN or chassis details before ordering.
