      This SFI 18.1 Approved Balancer is designed specifically for High Performance Big Block Chevys 

      External Balanced 

      Like all Innovators West Balancers, it features an all aluminum case design for light weight, stress-proof steel hub and 1040 steel inertia rings for durability.

      Wet clutch friction design style with precision machined harmonic dampening for street and race engines.

      The #104X damper is for any BBC making up to 2000 hp.

      For engines making over 1600  hp we reccomend an internal balanced engine. 


      • Flying Magnet Crank Trigger Option
        Get rid of your separate Crank Trigger Wheel by integrating it into the Damper itself! - Saves on average about 9 Ounces over the MSD Crank Trigger Wheel.
      • Crank Trigger Bracket Option
        BBC Crank Trigger Kit OptionBolt on a matching billet aluminum sensor bracket and mounting hardware, with either passenger (std) or drivers side mounting options.
      • Crank Trigger Sensor Option
        3/4-16 UNF Flying Magnet Crank Trigger Sensor - Direct Replacement for MSD #8276. Designed to work with Integrated IW Flying Magnet Balancer Option and Brackets.
      • Dual Keyway Option
        The double keyway option requires that the factory or aftermarket crankshaft be removed from the engine and a second keyway cut into the snout of the crankshaft. DO NOT run a double keyed damper on a crankshaft without the double keys. Failure to the damper hub can happen without the supporting key in the broached keyway slot. The dual keyway option is for Supercharged or Extreme Duty Applications (typically over 750 rwhp). Without the double key modification your crankshaft in these high horsepower applications can lead to the failure of the damper hub and/or the single keyway which results in damage to the damper and the crankshaft snout.
