BTR .660" Platinum Gen 5 LT1 Valve Spring Kit
BTR GEN V LT1 VALVE SPRING KIT - SK018
The BTR Platinum Spring Kit would be inducted into the LS Aftermarket Hall of Fame if such a thing existed. Whether you’re putting together a daily driver with a mild cam, a 600 hp N/A stroker, or a turbocharged 1000 hp brawler, our Platinum Spring Kit will make sure your valves are right where your cam wants them to be at all times. With that said, when the Gen V LT engines came out, we knew our Platinum Springs would be right at home on the direct injection platform with the correct supporting parts. They are designed to be used with stock rocker arms. This is a drop-in kit for Gen V LT1, L83, and L86 engines.
WILL NOT FIT LT4. See SK019 for LT4 applications.
