Installation Notes
Professional installation recommended. Correct spring heights and valve travel must be verified to avoid coil bind. For camshaft installations, always check piston-to-valve clearance and verify spring installed height. Use high-zinc break-in oil on first start.
This component forms part of the valve train system and must be selected to suit the intended engine configuration, RPM range, and camshaft design.
