The Speedmaster PCE272.1003 single valve springs feature a 1.490" outer diameter and are rated at 125 lbs at 1.800" installed height, delivering consistent seat pressure to keep valvetrain components firmly under control during operation. An integrated damper insert helps suppress harmonic resonance and spring surge, contributing to smoother, more stable valve motion across the RPM range.
With a coil bind height of 1.150", these springs provide a solid working window between installed height and bind, making them a dependable choice for engine builders seeking reliable valvetrain performance. Sold as a set, they are ideal for use in performance engine builds where precise spring specs are required to match your cam profile and cylinder head combination.
