Description

The BTR Platinum LS .660 Lift Dual Valve Spring Kit is engineered to deliver precise valve control for aggressive LS camshaft profiles, ensuring stable valvetrain operation at high RPM. Designed specifically for stock rocker arm configurations, this kit keeps your valves exactly where your camshaft intends, reducing valve float and maintaining consistent performance under demanding conditions.
 
This drop-in dual valve spring kit is compatible with Gen III and Gen IV 15° LS cylinder heads and installs without machining. For LS7 cylinder heads, proper installed height can be achieved using a .045" shim (SS015 + SS030).
 
Each component is precision-matched to work as a complete system, making this kit ideal for high-performance street, track-day, and race LS builds where durability and valvetrain stability are critical.
