When higher RPM, greater valve lift, stiffer spring pressures, and larger valve sizes exceed a single spring's capabilities, it's time to upgrade to a dual spring setup. Our American-made Dual Valve Springs provide the extra control you need, maintaining precise valvetrain motion and safeguarding against valve float. Step up to our Dual Valve Spring Kit for confident, stable valvetrain control in any high-performance diesel build.

Whether you're pushing higher RPM, boosting valve lift, or running more aggressive cams, these springs keep your engine on track for maximum power and reliability.
