ZZPerformance is constantly striving to make modifying your car more affordable and more reliable. Our latest product, 82# valve springs, does both.
These springs are compatible with all Ecotec 2.0, 2.2, 2.4 liter Ecotec engines.
.500" coil bind, 82# seat pressure 200# at .420" lift
Currently only available with titanium retainers.
Fitment note: As of 2023 GM modified the design of the Ecotec rockers (New PN: 12693909) making the valve stem side "taller". These new rockers may interfere with the titanium retainers and may need to be ground down. See photo for differences. When installing our valve springs and retainers with NEW rockers, verify fitment before final assembly. Any questions please email firstname.lastname@example.org
