PAC Racing - Solid Roller Dual Valve Springs - (1335)

The PAC Racing 1335 is the "BIG DADDY" severe duty, small diameter valve spring designed for solid roller camshaft requiring lightweight valvetrain. This spring is used in very high lift, upper range RPM or forced induction engines. Direct replacement for the other round wire 1300 series springs but with more spring rate than even the 1238X 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.
