HEMI 2-Step Launch Controller - Plug and Play - by MMX

MMX Plug and Play HEMI 2 Step Kit! Are you after more consistent launches on the track? Want your new turbo setup to spool faster? Do you just want your HEMI engine to make awesome 2 step sounds? MMX has you covered with our all-new HEMI 2 Step Kit.

This Kit fits all 2006-2024 5.7L, 6.1L, 6.2L, and 6.4L HEMI engines in any platform, with any transmission (Automatic or Manual). This can fit earlier engines with late model coil pack conversion. MMX has added enough wire length for the control box to be mounted in either the glove box, or center console of any late model Car, Truck, Jeep, or Durango.

Our team at MMX set out with one goal for this project; make the best and most complete HEMI 2 step kit on the market. Our all new PNP HEMI 2 step is just that, a COMPLETE FULLY PLUG AND PLAY KIT. The coil side of the harness, the activation button, and the power side of the harness are all fully PNP. See our PDF instruction photos to see just how easy this kit is to install! We include fuse taps for all 3 major fuse styles; NO SPLICING required! RPM Range on our 2 Step Kit is 1000-9900 in 25 RPM Increments, simply turn the adjustment knob to your desired setting, hit the activation button, and floor it!  Our Kit comes with a momentary button that is pre wired in a separate harness. The end user can add a microswitch under the break pedal if they like, and we also have a 0-5V pre terminated wire for future use (Left Steering Wheel Paddle Activation) more on this at a later date! For 2015-2023 Challenger, Charger, and Chrysler 300 owners, See our optional glove box mount. This makes mounting the controller very easy!

Note: This product requires your vehicle to be tuned to turn off misfire monitors and coil circuit monitoring, as with any 2-step launch controller.
