HIGH LOAD BEEHIVE SPRING KIT

FEULING HIGH LOAD BEEHIVE valve springs are a direct bolt in replacement, no spring seat or rocker cover machining required up to 0.565 lift. These springs will accommodate over 0.600 cam lift but will require spring seat pocket machining on the cylinder heads to set correct spring open height. Milwaukee Eight HIGH LOAD 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!
HIGH LOAD SERIES springs available for 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

Kits include: matched set of FEULING HIGH LOAD 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!
Quicker Revving - Smoother Motion - Light Weight Ti Retainers

ONLY recommended for large lift camshafts and RACE style engines as these valvesprings if not set properly will create extreme rocker arm deflection - See Feuling 592 grind cam #1348

Part # 1207 Fits: M8 with factory style 6mm valve stems and triple groove locks, this kit includes Ti retainers. These springs are ONLY recommended for large lift camshafts like Feuling #1348 592 lift and RACE style engines as these valvesprings have increased load and if used on smaller cams will create extreme rocker arm deflection
