Valve Springs, Dual, 1.430 in. Outside Diameter, 333 lbs./in. Rate, 1.150 in. Coil Bind Height, Set of 16

Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. COMP Cams valve springs are offered in single and dual styles to meet your cam requirements.
