Product Description

PAC Racing - LSX Severe Duty Dual Valve Springs (1207X)

The PAC Racing 1207X is a severe duty valve spring designed for lightweight LSx style valvetrain used in a high RPM or forced induction engine. Direct replacement for the 1205X spring but with more spring rate for heavier valvetrain and more RPM potential. Will fit most aftermarket cylinder heads with small 1.300" diameter dual spring packages. Round wire construction.

Don't buy imitation, low quality imported valve springs. Use only U.S.A. manufactured, premium quality  PAC Racing valve springs. Your engine's valvetrain will thank you.
