BTR Platinum LT1 .660 Lift Dual Valve Spring Kit

The BTR Platinum Valve Spring Kit for Gen V LV1 and LV3 V6 engines delivers the same legendary valve control that has made the Platinum Spring Kit a benchmark in the LS aftermarket. Proven across everything from mild daily drivers to extreme high-horsepower forced-induction builds, this spring package ensures your valves stay exactly where your camshaft commands, at all RPM levels.

When Gen V direct-injection engines entered the performance world, BTR engineered the Platinum Spring Kit to integrate seamlessly with the DI valvetrain architecture using the correct supporting components. This kit is specifically designed for stock rocker arms and installs as a true drop-in solution for Gen V LV1 and LV3 V6 cylinder heads, requiring no machining.

Ideal for naturally aspirated, boosted, and aggressive camshaft applications, this kit delivers the durability, consistency, and valve motion control demanded by modern Gen V performance builds.
