The Billet Flywheel w/Starter Gear built by ARC for the Honda or Clone GX340, GX390, 420, 440, 460 Big Block Engines.

The 6609 series flywheel is designed to use a B & S "Raptor" Coil.397358 or our Nology Profire coil an aftermarket high voltage performance coil #PFC-BS-2 CNC machined of 6061 Billet Aluminum with or without fins. Unless otherwise indicated, all ARC flywheels have our signature steel adjustable timing hub which allows at-the-track timing changes at 1В° increment in as little as 90 seconds without the use of offset keys or engine disassembly. The adjustable hub also makes it fast and easy to accurately set timing during engine assembly. Other outstanding features include • A 17% increase in voltage produced at the coil with a more accurate discharge of that current due to the aluminum body. • A 38% overall increase of voltage produced by the coil. ( 5hp dia Only -Larger diameter = faster magnet speed = higher voltage) • Forward Curve fin design optimizes fan efficiency. • Neodymium (rare earth) magnet is the most powerful on the market. • The timing hub also functions as an ingenious flywheel remover.
