High Load Beehive® Spring Kit
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
Valve springs are a direct bolt-in replacement, no spring seat or rocker cover machining required up to 0.565” lift
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
Smaller lighter weight retainers which drastically reduce the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs
Kit includes: 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
Fits factory style 6.00 mm valve stem and triple groove.

Feuling® BeeHive® valve springs must be installed at the correct open height, matching max lift to the open height spec of the valve springs
Made in the USA
Only recommended for large lift camshafts and race style engines as these valvesprings if not set properly will create extreme rocker arm deflection.
