Use with:
- 1.0 Ohm Ballast Resistor is recommended for most applications on street driven & high performance general purpose applications.
- This ballast resistor is recommended with most Mopar OEM (oil filled) or OEM-Spec coils.
- This ballast resistor is also recommended for use with HP Coil 555-40105.
Note: Ballast Resistors with less than 0.5 Ohm are only recommended for racing applications that run high RPM only & are not recommended for vehicles that idle for extended periods of time (i.e. 15-20 minutes) since this will overheat the ignition coil due to the longer dwell time at idle.
JEGS offers two options for ignition control on Mopar engines. Choose from the HiRev 7500® control unit with an OEM Appearance & modern electronics inside or the standard Orange control unit. The electrical connector on control unit plugs into all Mopar OEM and Mopar Performance wiring harnesses (both 4 & 5-pin harnesses). A replacement wiring harness and ballast resistor are also available to repair or upgrade the ignition system (sold separately).
JEGS EZ Kits are designed by JEGS professionals to ensure that you get all the correct parts you need.
