Beehive® high-load spring kit

CNC-machined from premium high-strength chrome-silicon wire with an oval cross-section, shot-peened and treated with the special NexTex® thermal process, ensuring these valve springs deliver durability commensurate with high
FEULING® BEEHIVE® valve springs utilise a smaller, lighter retainer, drastically reducing valve weight and allowing for faster response and smoother operation than conventional double or single springs.
Direct replacement valve springs, no seat or cover machining required up to 0.565" lift
The springs accommodate over 0.600" valve lift, but require head seat machining for the correct height
Lighter and smaller retainers drastically reduce valve weight, creating higher revving speed and smoother movement compared to double or single valve springs.
Eliminate valve spring separation, maximise stability, reduce noise and harmonics of the valve train
The kit includes: Feuling® High Load Beehive® combined valve spring set, titanium retainers, machined spring seats, washers, valve keepers and a set of premium Viton® valve seals with spring-loaded stem cleaning system

Recommended for camshafts with a lift of +0.540”
Feuling® BeeHive® valve springs must be installed at the correct OPEN VALVE HEIGHT, adjusting the maximum lift to the open valve height specification of the valve springs.
Manufactured in the USA
Recommended only for high-lift camshafts and racing engines, as these valve springs may cause extreme rocker arm deflection if not adjusted correctly.
EU: Valve springs are a direct replacement; no machining of the spring seat or rocker cover is required up to 1.435 cm lift.
EU: Springs support over 1,524 cm cam lift, but require porting of the spring seats in the cylinder head to adjust opening height
