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 available at checkout, which are the lightest available for LSx dual springs, weighing in at 8.5 grams, or 11 grams with locks.
This is a drop-in spring kit for the following engines: LS1, LS2, LS3, LS4, LS6, L76, L92, L99, LQ4, LQ9, L33, and LSA. Will fit LS7 Engines with the proper amount of shimming. This kit will not fit LS9 engines.
