Dual Valve Spring Kit - GM LS w/Ti Retainers

The Dual Valve Spring Kit - GM LS w/Ti Retainers from COMP CAMS is engineered for serious LS-series engine builders and performance enthusiasts seeking reliable, high-rate valve control. Designed specifically for GM LS platforms, this dual spring kit delivers the consistent lift and stability required in high-RPM applications where single-spring designs fall short. Whether you're building a street performer or track-focused engine, this kit provides the foundation for aggressive cam profiles and extended valve events.

Each kit features dual valve springs rated at 505 lb/in, paired with premium titanium retainers that reduce rotating mass and improve responsiveness compared to steel alternatives. The 1.100-inch coil bind specification prevents spring bind-up at maximum lift, while the 1.320-inch outer diameter ensures proper fitment within OEM and aftermarket LS cylinder heads. Viton seals protect against oil degradation, and the steel seat provides durable contact surfaces that withstand high cycle rates. This combination of materials and engineering delivers consistent valve seating and minimizes float across the RPM band.

LS engine builders, tuners, and DIY enthusiasts benefit most from this upgrade when pairing the kit with performance camshafts rated for higher spring rates. Installation requires proper valve spring compressor equipment and basic engine machine shop familiarity; professional installation is recommended to ensure correct seat pressure and preload. The dual spring design is compatible with LS1, LS2, LS3, LS6, and LS9 cylinder head applications. Weighing 5.25 lbs and packaged in compact dimensions, the kit ships ready for immediate installation on your next build or rebuild project.
