COMP Cams® Specialty Valve Springs

Single

  • Tensile testing, surface inspection and chemical analysis ensures springs are free of defects for optimum strength and durability
  • Manufactured from Super Clean™ wire to ensure materials are free of flaws
  • Engineered with advanced processing techniques to provide maximum valve control

Single Valve Springs from COMP Cams® allow you to build the perfect spring assembly for your application. The valve spring creation process is far more involved than most people realize. Selecting the right metal stock and creating the best design is not done by chance. COMP Cams® has developed a process that creates the highest quality valve spring available. A quality assurance process that utilizes three different methods, including tensile testing, surface inspection and chemical analysis, ensures springs are free of surface defects for optimum strength and durability. The result is a product that meets and exceeds the expectations of today’s engine builders and racers.
