BTR LT4 Conical Spring Kit - .650"

BTR LT4 CONICAL SPRING KIT - .650" - SK014
We were first to market with a conical valve spring kit for Gen V LT4s. Big whoop, right? WRONG. Weight is the enemy of a proper functioning valvetrain. If your cam isn't too radical, a dual spring kit isn't required. These springs will vastly improve valvetrain stability at high RPM while still supporting up to .650" lift. Made right here in the good ole US of A, this kit includes springs, locks, seals and locators. Uses stock retainers.
LT1/L86 engines require SK013.
Spring specs:
160 LB SEAT @ 1.875" INSTALL HEIGHT
395 LB OPEN @ 1.225"
COIL BIND @ 1.165"
Kit includes:
SP014-1 valve spring (QTY 16)
SL520045CON-16 locator set (QTY 1)
VS LS KIT valve seal set (QTY 1)
VL7°8MM-32 valve lock set (QTY 1)
NOTE - BTR does not recommend single wire conical or beehive springs with roller rockers due to the extra mass causing loss of valve train stability, or the use of a higher ratio rocker as it could possibly cause a coil bind issue. If you have a specific combination of valvetrain parts you are needing to use a roller rocker on, please call in to our sales team for clarification.
