EFI 36-1 Trigger Wheel

Part No.: AR402DM

Price: $225.00


AR402DM is a 6 bolt trigger wheel for EFI applications. The 36-1 tooth configuration is compatible with Holley HP and Dominator EFI systems. Use with AR177M  or AR226M crank trigger brackets and a Holley 554-124 sensor for a complete crank trigger solution. The AR402DM trigger wheel is a drop in replacement for the MSD trigger wheel. The AR402DM is 7.35 inches in diameter, 3/8 inch thick and includes a machined centering ring for the crank pulley. The 6 bolt pattern is evenly spaced. The TDC tooth is marked with a dimple, the 7th tooth after the gap is scribed with a line. A stock water pump housing may require some clearancing. Install with the engine at TDC and the sensor pointing at the line on the 7th tooth after the gap.
