ProCal SNAP for JL Wrangler and Gladiator truck is the latest addition to AEV's growing family of electronic calibration modules. This cost effective calibration module 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 depending on a lesser quality module. The ProCal SNAP also features TPMS functionality and is compatible with 2021 model year Wrangler/Gladiator (except 4xe – coming soon!).
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!
ProCal SNAP is proudly manufactured in the USA.
Note: ProCal SNAP is included with AEV JL/Gladiator suspension systems! 4XE compatibility coming soon!
