Options
-
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 Sensor Option
Direct Replacement for MSD #8276. Designed to work with Integrated IW Flying Magnet Balancer Option and Brackets. -
Crank Trigger Bracket Option
Bolt on a matching billet aluminum sensor bracket and mounting hardware with passenger (std) side mounting. -
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. -
Blower Hub Option
The super duty hub has increased material for supercharged applications.This increased material helps to protect the hub from cracking in high load applications. The super duty hub is recommended for supercharged applications making over 750 rwhp. Includes matching timing cover oil seal.
