AEV ProCal SNAP Recalibration Module for 2019+ HD Ram Trucks

AEV's ProCal SNAP for 2019+ HD Ram 2500 and 3500 trucks is a simple, cost effective calibration module that will accurately correct your speedometer after installing up to 42" large tires and/or changing the axle/transfer case gear ratio, saving you from the headaches and cost of going to the dealership's service department or purchasing unnecessary equipment. The ProCal SNAP even has the ability to adjust your TPMS threshold, a very important feature to have when running larger tires with less air pressure for more extreme adventures. After installing the included AEV Programming Harness, ProCal SNAP simply plugs into your vehicle's OBDII diagnostic port and interfaces with the user through the audio system equalizer. After inputting the necessary numerical values for the tire size or gear ratio through the audio equalizer (example: 35.5" tall tire = bass 3, mid 5 and treble 5) the settings are saved by pressing and holding a combination of buttons on the steering wheel. It's that easy... in fact, some might say it's a SNAP! This kit is proudly made in the USA and will not void your truck's factory warranty!
