Brian Tooley Racing BTR BTR-SK001/6560/BB/TS Features:

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. They are designed to be used with stock rocker arms. This is a drop-in kit for LS heads with bronze guides and features our tip saver kit for your worn valve tips.
