FEULING® ENDURANCE BEEHIVE® VALVE SPRINGS MAXIMIZE VALVE SPRING STABILITY REDUCE VALVE-TRAIN NOISE & HARMONICS!

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, lightweight Titanium heat treated 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.
