|
- 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. |

 | | COMP Cams® Specialty Valve Springs | Ovate Wire | |
|
- Oval shaped wire springs have more material in the same area as round wire to more efficiently distribute operation stresses
- Engineered for superior strength and durability to add valve train stability
- Super Clean™ wire material is free of surface defects that shorten spring life
|
| COMP Cams® Ovate Wire Springs are constructed from oval shaped wire as opposed to round. The unique oval shaped wire means there is more material occupying the same area than round wire springs to more efficiently distribute the operation stresses. Engineered with advanced processing techniques for longevity and reliability, Ovate Wire Springs are free of life-shortening surface defects. |
