FEULING 1108 ENDURANCE BEEHIVE VALVE SPRING KIT TITANIUM RETAINERS M8

W/Ti Retainers
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.

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 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, Ti 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.

Dont get stung by inferior valve springs!
