The GSC Power-Division Conical Valve Spring Kit with Ti retainer for 4G63T includes 16 titanium retainers and 16 conical valve springs. The GSC5079 kit is designed to work with the OEM spring seat or GSC1004. Able to use NEW OEM valve spring keepers or our GSC1003 keeper kit. No need for special aftermarket locks that have the potential of being the wrong angle. Conical springs allow for the use of a smaller, lighter retainer and have a varying spring rate allowing for higher RPM and more valve control.  GSC Power Division Pressure Conical Spring
