BTR Platinum Dual Valve Spring Kit
The BTR Platinum Spring Kit would be inducted into the LS Aftermarket Hall of Fame if such a thing existed. Whether youre 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. Designed to be used with stock rocker arms. Drop-in kit for 15° LS heads. It will also work with LS7 heads when used with a .045" washer (will not fit LS9 engines).
