2-Step Rev Limiter Launch Control Module
  • Fits 1997-2017 GM Gen III and Gen IV LS Engines
  • Plug-and-Play Factory Style Connectors
  • Works with 24x and 58x Trigger Wheels
  • Sets a Staging RPM Limit for Consistent Launches

    Getting a consistent launch out of a late-model LS car means holding the engine at a repeatable rpm while you stage. This 2-Step launch control module wires into a Gen III or Gen IV GM LS ignition system and adds a second, lower rev limit that stays active while the activation switch is closed, so you can hold the throttle down without over-revving and leave on the same rpm every pass.

    MSD 8733 2-Step Launch Control Module Features:

    • Adds a second, lower rpm limit used for staging and launching.
    • Connects to late-model GM LS engines using factory style connectors for a splice-free installation.
    • Compatible with both 24x and 58x crank trigger wheels.
    • Works on cars with manual or automatic transmissions.
    • Helps produce quicker, more consistent 60-foot times.

    Emissions Note:

    This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.

  • MSD 2-Step Launch Controllers connect right to your late model Ford or GM Modular to produce consistent launches and quicker 60-foot times by setting an rpm limit to stage with. When activated, the rpm will be held steady at your pre-set limit. The launch controller's rpm is easily adjusted with two built-in rotary dials ranging from 1,800-9,900 rpm in 100 rpm increments.
