Stealth Cylinder Head Valve Spring - Single Spring

Our performance valve springs are a single spring with damper design that feature about 130 pounds on the seat and 330 open. They work great with most smaller hydraulic flat tappet cams (we suggest checking with your cam manufacturer to find their requirements for the springs they recommend for use with your cam.) See the "specifications" table below for more detailed information on these. We offer them in either singles or complete sets of 16.
