Overview

The Chevrolet Performance LS6 LS9 Valve Spring Kit (SKU 19420455) is engineered to provide reliable performance for high-revving LS engines. Originally featured on the 2002 405HP Z06 Corvette, these springs were designed to complement a high-lift factory camshaft, making them an ideal upgrade for performance-oriented LS applications. This kit includes 16 single beehive-style valve springs, offering a direct-fit solution for most LS engines. They are rated to support a maximum valve lift of 0.570 inches. Key specifications include 90 lbs. of seat pressure at an installed height of 1.800", 295 lbs. of open pressure at 1.250", and a coil bind height of 1.160". This spring is noted to be the same specification as the widely used blue LS3/6/9 spring, though it may exhibit a color variation from the manufacturer. Installation details and compatibility should be confirmed with specific engine builds. The springs are manufactured by Chevrolet Performance. It is important to note that this product is subject to California Proposition 65 warning regarding potential cancer and reproductive harm.
