GSC titanium valve spring retainer set for 4G63 applications, supplied as a matched set engineered to work with beehive spring profiles. Titanium construction reduces reciprocating mass compared with many steel retainers and the set is specified for 4G63 beehive spring setups where lighter retainers are desired to support higher engine speeds and improved valve control.
