The GSC conical valve springs act as a natural harmonic damper in the transfer of valvetrain shock to reduce stress and wear resulting in longer lasting valve components.
These springs feature a superfinished surface treatment in addition to their multi step heat treatment process to provide substantial increases in strength and durability.
Each kit comes complete with a full set of conical springs, titanium retainers and shims.
