Advanced Beehive Valve Spring Technology
Comp Cams Beehive Valve Springs are revolutionizing performance street/strip applications! These valve springs deliver increased valve train stability while offering a reduction in weight. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and the retainer. Using Comp Spintron testing equipment, the Beehive spring was engineered to maximize "harmonic resistance" through reduced mass and unique coil spacing. With highly reduced internal spring harmonics, engines equipped with these state-of-the-art Beehive valve springs rev higher and live longer as compared with other "performance" springs. For street/strip applications, these valve springs are the best choice possible. Because of the unique Beehive design, the valve train can handle more rpm and more aggressive cam profiles for occasional bracket racing but still retain durability for street driving.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
