Frequently Asked Questions

How many seals are in one pack?

Four seals — enough for one complete engine with spares, or two engines.

Will these fit my 1984+ Shovelhead?

This part is specific to 1978-1983 Shovelheads. Later models may use different seal dimensions.

What makes Viton better than standard rubber seals?

Viton resists high heat and combustion byproducts, preventing oil seepage that can cause carbon buildup and power loss in the combustion chamber.

Do these require special installation tools?

Valve stem seals require removal of the rocker box and pushrod tubes — a professional mechanic or experienced builder should handle installation.
