ENDURANCE BEEHIVE VALVE SPRINGS W/O Ti retainers Milwaukee Eight 17

  • FEULING® ENDURANCE BEEHIVE® valve springs are a direct bolt in replacement, no spring seat or rocker cover machining required. Endurance springs are 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.
    • Eliminate valve spring separation, maximize stability, reduce valve-train noise & harmonics!
    • Available for 5/16, 7mm and 6mm valves
    • FEULING® BEEHIVE® valve springs are packaged as a matched set and must be installed at the correct OPEN HEIGHT. Matching max cam lift to the open height spec of the valve springs is essential for optimal valve-train operation and spring life. See included spring spec chart
    • FEULING® endurance springs are a direct bolt-in replacement on EVO/Twin Cam up to 650 cam lift and Milwaukee Eight up to 565 cam lift with no machining or rocker box clearancing required.

    Kits include: matched set of FEULING® ENDURACE BEEHIVE® valve springs, machined spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with a spring loaded valve stem wiper system. THIS KIT USES THE FACTORY STOCK STEEL RETAINERS, if Ti retainers are desired see spring kit #1108 or Ti retainer kit #1109

    Dont get stung by inferior valve springs!
