239482 Racing Tappet Guide Set of 4

This Jims billet racing tappet guide is a specialized performance component designed for high-output 4-cam engine builds. As a racing version of the ZPN235812 guide, this part is intended for custom applications requiring extreme clearance, accommodating a lift of approximately .800" at the valve or .500" at the cam. To maintain structural integrity in competition environments, the design omits oil grooves and pushrod tube cover bores. Machined from billet material, it provides the precision and durability necessary for modified engines. Jims components are trusted by engine builders for their exacting standards and specialized racing hardware.
