Feuling Endurance Beehive Valve Spring Kit For Harley

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. 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.

Features:

• Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics
• Light weight Ti retainers
• Dont get stung by inferior valve springs
• Quicker revving
• Smoother motion
• Bolt in up to 650 Lift
• Made in the U.S.A.

Kits include valve springs, lightweight 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.
