Dual Valve Spring Kit - GM LS w/Ti Retainers

The Dual Valve Spring Kit - GM LS w/Ti Retainers is designed for serious LS-series engine builders and performance enthusiasts who demand reliable valve control in high-RPM applications. This dual spring kit is specifically engineered for GM LS platforms, providing the stability necessary for performance builds, whether for street or track use.

Featuring dual valve springs rated at 505 lb/in and premium titanium retainers, this kit reduces rotating mass and enhances responsiveness compared to traditional steel options. The 1.100-inch coil bind specification prevents spring bind-up at maximum lift, while the 1.320-inch outer diameter ensures compatibility with both OEM and aftermarket LS cylinder heads.

Engine builders, tuners, and DIY enthusiasts will find this kit beneficial when paired with performance camshafts that are compatible with higher spring rates. Proper installation requires valve spring compressor equipment and familiarity with engine machine shop practices, and professional installation is recommended to achieve the correct seat pressure and preload.
