FEULING PARTS Beehive Valve Springs - Harley-Davidson '84-'04 - 1100

FEULING ENDURANCE BEEHIVE valve springs are a direct bolt in replacement up to 650 lift camshafts no spring seat machining required. 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 much smaller and lighter weight retainer which drastically reduces the valve weight creating a much quicker revving and smoother motion than comparable dual valve springs.
FEULING endurance springs are a direct bolt-in replacement up to 650 cam lift no machining or rocker box clearancing required.
Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
Available for 5/16 and 7mm valves
FEULING BEEHIVE valve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs

Kits include: FEULING ENDURACE BEEHIVE valve springs, lightweight 7 Degree Titanium heat treated 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.
