American Made Titanium Retainers


The ultimate in lightweight and strength. When you upgrade from steel to titanium valve spring retainers you gain speed and power, because titanium retainers are lighter and stronger than steel. Manufactured to precise tolerances of special 6AL 4V titanium for maximum strength and durability. Up to 50% lighter than steel retainers. Lighter means less chance of valve float. Sets of 16.
