Performance 24 Valve Springs
Stock 24v springs allow the intake valve to blow open at 50psi. on the bench. This is a major problem and it is intensified as temperatures and rpm increase. With high drive pressures your engine might even be experiencing reversion, when the exhaust valve blows open on the intake stroke contaminating the intake charge. Get Control of your valvetrain with our springs and pushrods. Our 24 valve springs are designed to work with your factory retainers and locks, and have a Beehive design to reduce mass on the end with most linear motion. They also help increase initial acceleration of the valve. They are made with the highest quality ovate wire to handle cams with higher lift. They coil bind .111” after the stock springs, and have been triple shot-peened and nitrided to reduce internal stresses, prolong life and prevent corrosion, The BEST springs on the market at an affordable price. For use with all 24v Cummins from 1998.5- present 5.9l and 6.7ll engines. If you are using a cam with over .320” lift call and check on the availability of a new spring designed for slightly lower high lift pressures. Aftermarket retainers and locks are not needed on 24v engines using Hamilton #110 springs.
