At COMP Cams®, we learn by testing everything we build, both in the lab and in the field. A perfect example of how this testing program yields beneficial results is the revolutionary Beehive™ valve spring technology that has taken automotive performance enthusiasts by storm. These advanced valve springs provide increased valve train stability and revving capability; now that same technology is available for your Harley-Davidson engine. Using COMP® Spintron testing equipment, the #26120 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.
