Using a lightened flywheel with a stock, non counterweighted crankshaft requires using a GB 440AE Equalizer pulley to dampen harmonics, bending, torsional twist and vibration. Without doing so can cause premature case, piston, rod bearing, and even possible crank damage. Note: If you require a 6 volt ring gear on the flywheel, purchase GB 085, LA BAL017 and LA FLY030 in addition to the flywheel itself. |
