Product Description

    Details

    Supertech performance valve springs are made with premium Super clean Chrome Silicon Vanadium Steel Alloy for higher performance and durability. Computer designed to ensure that wire stress levels do not overpass the limits for long durability under extreme conditions and harmonics are well under control.

     

    Supertech Retainers are manufactured with high quality military certified Titanium alloy, CNC machined for a tight fit that will ensure a long durability.

    This is a popular spring for the Ecotec platform but some users have reported failed valve seals after running them.  We recommend ZZP 82# valve springs for all Ecotec builds to avoid potential issues, however we do offer these due to market request.  More information can be found with a google search
