Raise the lift on a HEMI and the stock seal can end up in the way of the retainer before the valve is fully open. These metal body seals use a Viton element in a compact steel body, so they keep oil out of the port at high rpm while leaving the spring and retainer room to travel.

COMP Cams 532-16 Metal Body Viton Valve Stem Seal Features:

• Fits 2003 to 2008 Dodge 5.7L HEMI and 6.1L HEMI engines.
• Sized for 5/16 in. valve stems and 0.530 in. O.D. valve guides.
• Viton sealing element holds up to heat and high rpm oil control demands.
• Metal body construction stays located on the guide under repeated cycling.
• Compact height improves spring and retainer clearance on high lift combinations.
• Sold as a set of 16 seals, enough for a complete HEMI cylinder head pair.
