- 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 gradeHi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processedthermal heat treat and super NexTex finish to give these valve springs the needed fatigue lifeto 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.
