World Performance Valve Springs

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 rpm to 8,000 if you do not have the correct springs. Use only the valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. These World Products replacement valve springs are offered in single and dual styles to meet their cam requirements.
