    Ballast Resistor

    • 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.

    Rated 3 out of 5 by from It is what it is It is advertised as a 1.0 ohm resister but actual resistance is 1.8 ohms (at 70degrees).

    Rated 1 out of 5 by from Wrong Ohm mesurements I bought 2 of these for my RoadRunner. They were supposed to be 1 ohm resistance, but when I measure them with my ohm Meter, with alligator clips, no human touch to change resistance, they both measured out at 1.5 Ohm. They were only $9.99 Each, but JEGS charges the $11 return for parts, so it's not worth sending back. I'll just throw them away because they are useless as a spare. I bought a MSD resistor that was twice the price, but the 0.8 Ohms rating on that resistor, measured out to 0.8 Ohms correctly.
