AEV ProCal SNAP for 2019-2024 Ram HD

ProCal SNAP module for the 2019-2024 HD Ram (incl. 4500/5500) is a simple, cost effective calibration module that will accurately correct your speedometer after installing larger tires (up to 42" tall) and/or changing the axle/transfer case gear ratio, saving you from the headaches of going to the dealership or purchasing unnecessary equipment. The AEV ProCal SNAP Module for Ram 2500/3500/4500/5500 even has the ability to adjust your TPMS threshold, a very important feature to have when running larger tires with less air pressure. After installing AEV's Programming Harness (included), 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! AEV ProCal SNAP is proudly manufactured in the USA.
