The GX 340/390 engine has grown in popularity to the point that we were able to produce a more specific flywheel body to this engine. One major change is that these flywheels are designed to use the stock coil, and don't require any coil bracket. Both flywheels are SFI certified and have integral billet cooling fins.
We have two new models and they will replace our previous models.
First, the 6623. This flywheel is basically a billet replacement for the stock flywheel and plastic fins. The keyway is in the stock position and it is designed to use the stock pull starter. $195.00
The 6622 also has ARC's steel adjustable timing hub and a bolted-on ring gear made of super strong 7075 billet aluminum for the on-board electric start. Some adaptation is required if you also want to be able to use the pull starter. $250.00
