Supercams are a better design for medium and large cams (1½" and up). The asymmetric cam lobes give almost twice the range of conventional cams, and they are more stable than symmetric cams of the same size. Innovative spring technology gives precise, equally-tensioned trigger pull throughout the entire range, and the Kevlar trigger material is light, strong and field maintainable. Range Finder tells you at a glance if you've chosen the right size cam for the placement. Supercams feature an optimized cam angle and wider cam faces for greater holding power. The U-shaped body provides greater durability and unparalleled control during placement and retraction. CNC machined for much greater precision than stamped or extruded cams.
