ARC 36# Single Valve Spring for Modified Clone Engines

Push boundaries with the ARC 36# single spring, rated for extreme RPM in modified Clone and compatible engines, delivering unwavering control where stock parts falter.

• 36lbs pressure at .850" for solid valve seating
• Coil bind at .450" to fit tight heads
• Suits BSP 196cc, GX200, non-Hemi 212cc; not for stock valves

For racers chasing 9,000 RPM glory, this spring prevents float, ensuring valves snap shut precisely for optimal fill and fire—key to surging past competitors. Note: Hemi 212cc needs pocket mods. Pair with stainless valves and proper retainers for a setup that thrives under pressure.

Not for stock configurations. Its arc design sheds weight without sacrificing strength, aiding quicker revs and track dominance.
