ULTRA-LIGHT SS VALVE SPRING for 22XX, DISCOVERY & CHALLENGER
This ultra-light valve spring is made of stainless steel. It's .875" long with closed ends ground flat for smooth even compression. It's a perfect fit for Crosman 2240, 2250, 2260, 2300T, 2300S, 2300KT, 2400KT, Challenger, Benjamin Discovery and Sheridan 2260MB. It produces a small increase in power and will last indefinitely without corrosion. It helps produce a lot more power when used in combination with our other upgrade parts like power adjusters, hammer springs and longer barrels.
