ProCal SNAP Module

Calibrating the speedometer in your Jeep Wrangler JL or Gladiator JT is easy with the plug-n-play AEV ProCal SNAP Module. Installing the included harness and plugging the ProCal SNAP Module into the Jeeps OBDII diagnostic port lets you utilize the factory stereo display to make the adjustments. Equalizer settings on the touch screen display can be set for your tire diameter, axle gear ratio, and even transfer case gear ratio.
