Common questions
What is the +0.003 inch oversize specification?
This means the guide's outer diameter is 0.003 inches larger than a standard guide. It's used when the cylinder head's original guide bore is significantly worn, requiring more material to be removed for a tight press fit.
Will this fit my Shovelhead?
Yes, this KPMI intake valve guide is designed to fit all Harley-Davidson Shovelhead engines from 1966 through 1977. It also fits Panhead engines from 1948-1965.
Is this for an intake or exhaust valve?
This specific part is an intake valve guide. Exhaust guides are different and must be ordered separately if needed.
