Feuling 1207

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 may 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.

ONLY recommended for 0.540+ 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 or 618 grind cam #1352.

FEULING BEEHIVE valve spring kits are each hand measured and labeled specifically based on their coil bind / required open height. Our kits require you to measure installed height and may require use of included shims.
This is so you can set up the springs specifically to your camshaft lift for quieter and smoother performance. Similar to tuning your suspension to your weight and riding style.

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

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!
