The Supertech dual valve spring kit for GM Ecotec 2.0L engines is provided as matched inner and outer springs and specifies the need for a smaller valve stem seal. Intended for Ecotec heads that call for dual springs, this kit is used during rebuilds or spring replacement jobs; ensure the smaller seal requirement is addressed during installation to match factory fitment.
