1.320 Dual Valve Springs GM LS Engines

The 1.320 Dual Valve Springs for GM LS Engines are engineered for high-performance applications where valve control and reliability are crucial. Designed by COMP Cams, these dual springs cater specifically to the demands of modified LS platforms, making them ideal for street machines, race engines, or high-revving projects.

These dual valve springs combine an outer and inner spring with different rates and preload characteristics, providing superior control over valve motion across the entire RPM range. This configuration effectively resists valve float, which can compromise engine performance at high RPMs, while also reducing stress on valve seats and rocker arms. Crafted from high-quality steel, these springs undergo precise winding and stress-relieved heat treatment to ensure consistent preload pressure and longevity.

Ideal for tuners installing larger cams or builders of supercharged and turbocharged engines, these springs offer compatibility with both factory and aftermarket valve spring seats without requiring costly modifications. Whether you're pushing the limits of your LS engine or simply looking to enhance performance, the 1.320 Dual Valve Springs are a reliable choice for any enthusiast.
