Just because you're running a BDS Style Blower doesn't mean you have to run a solid hub, you can STILL run a Damper and SAVE YOUR CRANK!

This SFI 18.1 Approved Balancer is designed for BDS (Blower Drive Services) and other Roots Blower Pulleys to bolt right up. It features all aluminum case design for light weight, stress-proof steel hub and 1040 steel inertia rings for durability. Wet clutch friction style precision machined harmonic dampening for street and race engines.

This model is made for Short Snout Crankshafts. When running a stock length long crankshaft snout, please use #216 damper.

  • Crank Trigger Bracket Option - Add $136.00
    BBF Crank Trigger Kit OptionBolt on a matching billet aluminum sensor bracket and mounting hardware, with either passenger (std) or drivers side mounting options.
  • Dual Keyway Option - Add $20.00
    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.
