BTR LT4 CONICAL SPRING KIT - .650" - SK014 WITH TIP SAVERS!
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)
Due to the nature of the OEM scroll-type rocker arms, use of higher lift cams and higher-than-stock spring pressures can accelerate valve tip and rocker arm pad wear.
BTR's new valve tip saver kit incorporates our newly designed BTR valve locks (and BTR retainers in certain applications) in conjunction with GM lash caps, to help save valve tips, eliminating costly repairs that require cylinder head removal and replacement of damaged valves.
NOTE: If you already have excessive wear on the rocker arm pad, you must replace these at time of install.
NOTE: Due to the use of lash caps, pushrod length must be verified to achieve the proper lifter preload.
