FEULING 1107 ENDURANCE BEEHIVE VALVE SPRING KIT M8 

 

  • 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 engines from stock to performance.

    This FEULING BEEHIVE valve spring kit use the factory steel retainers.

    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 valvetrain operation and spring life. See included spring spec chart.

    FEULING ENDURANCE SPRINGS are a direct bolt-in replacement up to 565 cam lift with no machining or rocker box clearancing required.
    FEULING HIGH LOAD SPRINGS are good up to .650 lift machining may be REQUIRED depending on cam lift.

    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
