Valve Spring Kit - GM LS Beehive

The Valve Spring Kit – GM LS Beehive from COMP CAMS is purpose-built for LS-series engine builders and enthusiasts seeking reliable valve control under aggressive cam profiles and high-RPM conditions. Whether you're upgrading a stock LS platform or developing a dedicated race engine, this complete spring assembly replaces worn or insufficient OEM springs with a high-performance alternative designed to maintain valve sealing integrity and prevent float across the entire RPM range.

This kit features 313 lb/in spring rate Beehive-profile springs paired with chromoly retainers, Viton seals, and steel valve locks—each component engineered for durability and thermal stability in high-output applications. The 1.100 inch coil bind specification and 1.055 inch / 1.290 OD dimensions ensure proper installed height and clearance on LS cylinder heads, while the steel seat provides consistent contact pressure without degradation. Beehive design reduces resonant frequencies and spring surge, offering superior control compared to traditional cylindrical springs, particularly valuable when pairing with high-lift camshafts or extended valve events typical in supercharged, turbocharged, or naturally aspirated builds exceeding 6,500 RPM.

Most benefit comes to street and street/strip LS owners stepping up from factory springs or installing aftermarket camshaft profiles that demand additional spring pressure for reliable valve control. Installation requires standard valve spring removal and installation tools; verify your specific LS head variant (Gen III, Gen IV, LS7, etc.) before purchase, as retainer and spring seat dimensions may vary. This complete kit eliminates the need for sourcing individual springs, retainers, and locks separately, streamlining both the build timeline and quality assurance for serious engine builders.
