FEULING OIL PUMP CORP. High Load Beehive® Spring Kit [1207]

Description

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” (EU: 1,435 cm) lift
• Springs will accommodate over 0.600″ (EU: 1,524 cm) 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
• Kits include: 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
• ONLY recommended for large lift camshafts and RACE style engines as these valvesprings if not set properly will create extreme rocker arm deflection
