Rear Main Seal 80x98x10mm

The Honda 91214-RNB-A01 is a genuine OEM rear main crankshaft seal, manufactured by Arai, an OEM supplier for Honda. This seal is designed to be a direct, factory-replacement part, ensuring it matches the original material, dimensions (80x98x10mm), and fitment tolerances for K-series and a wide range of other Honda and Acura engines. This critical component is located between the crankshaft and the transmission bellhousing and is a frequent source of oil leaks on high-mileage K20 and K24 engines. Replacing the rear main seal is standard practice during engine rebuilds, clutch swaps, or when addressing crankshaft oil leaks, as it is a part best installed only once to avoid repeat transmission removal. Recommended for installation whenever the transmission or engine is removed, this seal ensures proper lubrication and prevents leaks. The product listing is for the seal only; gaskets, installation tools, and other components are sold separately. The seal is compatible with numerous Honda and Acura models, including specific years and engine codes for the Acura ILX, RSX, TSX, TL, RL, NSX, Legend, and Honda Accord, Civic, CR-V, Element, Fit, and HR-V. Always verify your engine code before ordering, as this seal fits multiple Honda engine families.
