The PAC Racing 1209X is the "big daddy" extreme duty valve spring designed for lightweight LSx style valvetrain used in very high lift, upper range RPM or forced induction engines. Direct replacement for the other round wire 120x series springs but with more spring rate than even the 1208X for camshafts that have some "big lobes" on them. Will fit most aftermarket cylinder heads with small 1.300" diameter dual spring packages but check the rest of your hardware to be sure. Round wire construction.
