Sealed Power Valve Springs

Valve springs are one of the most critical and overlooked components in your engine. Use these Sealed Power valve springs to be matched to your cam and help your engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 7,000 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. Sealed Power valve springs are offered in single and dual styles to meet their cam requirements.
