How to Confirm This Part Fits Your Vehicle

Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against RKN20621 number by WABCO listed above, and check the dimensions or specifications against your original part.
