Brian Crower Polaris XP Turbo/XP 1000 Valve Stem Seals Guides BC3990

Genuine Brian Crower performance component.

BC valve stem seals are designed for standard aftermarket valve guides like BC3965.

The seals allow a carefully defined amount of engine oil from the cylinder head into the combustion chamber—to lubricate the rotating valve stem in the valve guide.

BC valve stem seals are produced from high performance materials for increased part life and lower wear.
