V-Thunder hy-rev hydraulic tappets limit plunger travel, to allow for higher RPM operation with the quiet and precision of hydraulics. V-Thunder Hy-Rev hydraulic tappet features a unique anti pump race retainer. Tappet is designed to replace the normal clip, so as to precisely limit travel of the plunger during operation. This allows the valve train to perform more like a mechanical stern, allowing higher RPM operation with the quiet and precision of hydraulics.
