BTR LT1/L86 CONICAL SPRING KIT - Brian Tooley Racing - SK013

We were first to market with a conical valve spring kit for Gen V LT engines. 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. This kit includes springs locks seals and locators. Uses stock retainers.
