COMP Cams 1.589" Beehive valve springs suit high-lift solid flat-tappet and hydraulic-roller camshafts, with a .750" maximum lift and a design commonly used in Harley-Davidson engines. The beehive shape lowers retained mass for better valve control, reduces damaging harmonics, and improves high-RPM stability and durability for street and track applications that demand lighter valve-train dynamics.
