Feuling Endurance Beehive Valve Spring Kit For Harley
Feuling Endurance Beehive valve springs are a direct bolt in replacement. 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

Dont get stung by inferior valve springs

Quicker revving

Smoother motion

Made in the U.S.A.
