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.
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.
