Show original supplier description

The PSI 1511 ML is a lightweight beehive valve spring, weighing only 65 grams, and is Katech's standard selection for their engine packages. Optron valvetrain dynamics testing identified this spring as the optimal choice for effectively controlling lightweight valves, such as those found in LS6 and LS7 engines. With a spring O.D. of 1.290 inches and an outer I.D. of 0.630 inches, the PSI 1511 ML provides a seat pressure of 130 lbs at 1.800 inches and 370 lbs at 1.175 inches. It has a rate of 384.0 lbs/in and a maximum lift of 0.625 inches. Katech advises a coil bind clearance of .050 inches, which enables the use of this valve spring at lift heights up to .650 inches. The coil bind height is 1.10 inches. This valve spring is designed for LS, LT1, L83, and LT4 engines, provided that proper hardware is utilized.
