One of our favorite aspects of this kit is that the tool steel retainer is the lightest steel retainer made for 1.300" dual springs, only weighing 13.9 grams or 16.4 grams with locks. Those looking for the lightest valvetrain possible should upgrade to the optional titanium retainers, which are the lightest available for LSx dual springs, weighing in at 8.5 grams, or 11 grams with locks.
