2024 Jeep Wrangler Parts

Take complete control of your 2018–Present Jeep Wrangler JL’s electronic systems and performance. Superchips delivers advanced wireless calibration and custom tuning engineered specifically for the JL platform. Easily correct your speedometer for larger tires, optimize axle gear ratios, manage trail features, and unlock extra engine power across 3.6L Pentastar, 2.0L Turbo, and 3.0L EcoDiesel models.

Precision Speedometer Calibration and Gear Optimization

Upgrading your 2018–Present Jeep Wrangler JL with aftermarket wheels, off-road tires, or upgraded axle gears throws off your factory speedometer, shift points, and electronic stability control. Superchips calibrators—including the Flashcal for JL and the wireless Flashcal+—provide quick OBD-II speedometer recalibration for tire sizes up to 40 inches and axle ratios up to 5.38:1. Each JL kit includes the required Security Gateway (SGW) bypass module, ensuring seamless integration with your Wrangler's factory body control module.

Wireless Control and CRAWL Trail Management

Built for maximum versatility on and off the grid, Superchips’ app-based solutions like the Flashcal+ give you live control over key JL subsystems straight from your smartphone via Bluetooth. Activate the live CRAWL Screen to control differential lockers, disconnect sway bars in 2HI/4HI, adjust TPMS warning thresholds for low-pressure tire airing, and bump up engine idle RPM for winching. You can also customize daily driving preferences like Auto Start-Stop memory, daytime running light (DRL) configurations, and read or clear Diagnostic Trouble Codes (DTCs).

Unleash Engine Performance and Throttle Response

For drivers seeking power gains beyond speedometer calibration, Superchips Flashpaq F5 and Pulsar / Pulsar XT modules deliver horsepower, low-end torque, and sharper throttle response for 3.6L V6, 2.0L Turbo, 3.0L EcoDiesel, and 392 V8 engines. Pre-loaded performance tunes optimize fuel and timing maps for daily driving, towing, and crawling on the trail. Transmission shift strategy refinements eliminate gear hunting on 8-speed automatic models, keeping your JL in its ideal powerband whether on the highway or off the beaten path.
