We offer our brand new heavy-duty billet flywheels in a Hemi 8 bolt version. Use our 129-1054 bolt kit to attach these to the crankshaft. These are fully CNC machined from high quality 1045 super hard billet steel. The ring gear is made from high manganese carbon steel for accuracy and superior wear resistance. Works with 10.5 inch clutch only. These are setup for internal (zero) balance, (no external weights.)
Ring gear is 130 tooth, weight is 27 pounds, and the overall diameter is 13.19 inches. The diameter of the machined face (without the ring gear) is about 12.5 inches. The larger of the two bolt patterns measures 11 5/8" across (bolt hole center to center) and has 6 bolts evenly spaced around the outside of the wheel.
