Replacing all seals as a complete set during any upper unit service is best practice and prevents repeat disassembly from a single missed seal.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eFitment varies by engine make, model, horsepower, and year — always verify compatibility against the Sierra application guide before ordering.
