2013 Jeep Wrangler Parts

Maximize Performance and Speedometer Accuracy for Your Jeep JK

Upgrading your 2007–2018 Jeep Wrangler JK with larger off-road tires, suspension lifts, or aftermarket gear swaps instantly impacts your speedometer readings, shift points, and overall drivability. Superchips programmers—including the Flashcal, Flashcal+, and Flashpaq F5—provide effortless speedo recalibration for tire sizes up to 42 inches and axle gear ratios up to 5.38:1. By restoring proper computer parameters, your Wrangler’s automatic transmission shifts correctly, eliminating gear hunting and sluggish acceleration.

Off-Road Control and Trail-Ready Features

Conquering tough trails requires total control over your rig's electronic systems. Superchips devices unlock specialized CRAWL features specifically engineered for the Jeep JK platform. Control front and rear differential lockers, adjust TPMS thresholds for lower trail tire pressures, and temporarily raise engine idle RPM for winching or running high-draw electrical accessories. With real-time monitoring and live diagnostics via touchscreen or smartphone integration, you get total visibility over critical vehicle parameters wherever the trail takes you.

Custom Tuning and Vehicle Personalization

Beyond speedometer calibration and trail utility, Superchips pre-loaded performance tunes optimize fuel maps and timing curves for 3.8L and 3.6L Pentastar V6 engines. Enjoy noticeable gains in horsepower, low-end torque, and throttle response whether towing or highway cruising. Additionally, Superchips allows you to customize daily driving settings—such as daytime running light configurations, sway bar disconnect behavior, and reading or clearing Diagnostic Trouble Codes (DTCs)—giving you complete command of your 2007–2018 Jeep Wrangler JK.
