High Load Beehive Spring Kit

Machined from a premium grade Hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treat and super NexTex finish to give these valve springs the needed fatigue life to exceed the high demands of V-Twin engines from stock to performance

FEULING BEEHIVE valve springs use a smaller lighter weight retainer which drastically reduces the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs

Valve springs are a direct bolt-in replacement, no spring seat or rocker cover machining required up to 0.565 lift

Springs will accommodate over 0.600″ cam lift, but will require spring seat pocket machining on the cylinder heads to set correct spring open height

Smaller lighter weight retainers which drastically reduce the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs

Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics

Kit includes: matched set of Feuling High Load Beehive valve springs, Ti retainers, machined spring seats, seat shims, valve locks and a set of premium Viton valve seals equipped with a spring loaded valve stem wiper system
