Common questions
What does +0.001 inch oversize mean for installation?
The guide is 0.001 inch larger in diameter than a standard guide, allowing it to fit snugly into a cylinder head bore that has experienced slight wear, often without requiring additional reaming of the bore.
Will this valve guide fit my specific Harley-Davidson Twin Cam model?
This intake valve guide is designed for Harley-Davidson Twin Cam 88 and 103 cubic inch engines from 2005-2011. Please confirm your engine displacement and model year using our Shop by Bike tool before ordering.
Is this guide for both intake and exhaust valves?
No, this specific guide is for the intake valve position only. Exhaust valve guides are different and must be ordered separately.
