EFI Trigger Wheels

GM 7x Trigger Wheel

The GM 7x trigger wheel is bolted on to the harmonic balancer or pulley for lower HP models and can only be used with the traditional DIS setup.  The harmonic balancer can also be drilled with the 7x pattern if A/C option is used.

 

This will bolt in its place on the HB or pulley for lower HP models.   .  The 36-1 can only be used on Gen2 type EFI systems.

**If you are using for an FC, the trigger wheel will only fit using a pulley or you will need a 64 type rear bracket.  If using a pulley, DO NOT use the spacers provided in kit

 

Did I mention Brown EFI is for off-road use only?
