COMP Cams® .515” Lift Valve Spring Kit for Ford 6.0L/6.4L Power Stroke Engines

COMP Cams® introduces a premium valve spring kit for Ford 6.0L/6.4L Power Stroke engines that handles aggressive cams up to .515" lift and much higher boost pressures and RPM than factory valve springs.

COMP Cams® engineered the valve springs to have increased spring rate, as well as higher seat load for much better dynamic stability than factory springs. Unique ovate spring wire was selected to better manage operation stresses, create additional dynamic control and help valve train reliability at elevated RPM and boost pressures.

The spring kit includes the COMP Cams® Part #26124 Ovate Wire Valve Springs, #535 valve seals and #4809 shims while making use of your stock retainers. Springs are also available as a set of 32 pieces or in single units without the valve seals and shims.
