Fits 2003-2008 5.7L and 2005-2010 6.1L Gen III HEMI Engines
Restore proper valve stem sealing with the Michigan Motorsports Top Hat Viton valve stem seal set for early Gen III HEMI engines.

Durable Viton construction resists high temperatures and oil exposure, supporting reliable sealing under demanding engine operating conditions. Supplied as a set of 16, these seals provide the quantity needed for one supported HEMI engine during cylinder head service, engine rebuilds or replacement of worn factory seals. OEM interchange references include Mopar 5037798AA and 53021578AA for the corresponding applications.
