That crank pulley zero gram balanced which is substantially better balanced than the factory crank pulley. Please stick to the facts and stop perpetuating an urban myth.Thanks
Simple physics. In order for all the torsional motions and frequencies created from the engines operation a damper must be one with the crankshaft. Simply stated previously that means the damper must be interference fit to the said crankshaft. If the damper is not interference fit it will move...
- The balance shafts help all the other internals by counteracting many of the damaging harmonics. I would say that unless your building a race motor for non-street use install the balance shaft. Not having the stock pulley will make no difference unless you are really pushing the power envelope...
A tighter balance of the rotating assembly will be necessary but the engine will never run as smooth or quiet without the shafts.May as well stick with the stocker if you belive the damper myth cause the ATI and the Fluidampr are a waste since they don't do more than the stocker since they...
Just wanted to answer the original question since all the experts neglected to handle it. We specifically provide the part#'s of the smaller belts you will need when running our pulley sets on the 4G63. You are likely at the end of the tensioner throw and when everything is cold the belt is just...
