Enginetech S553V-20 Valve Stem Seal Set +0.020" Oversize OE Style

Manufactured to original equipment specifications, these seals help control oil consumption and protect valve guides from premature wear, making them an essential component in any quality engine rebuild or valve job.

• +0.020" oversize — designed for reamed or reconditioned valve guides
• Helps eliminate valve guide oil leakage and reduce blue exhaust smoke
• Manufactured by Enginetech, a trusted name in engine rebuild components
