2020 Jeep Gladiator Parts

Speedometer Recalibration and Gear Ratio Optimization

Upgrading your 2020–Present Jeep Gladiator JT with larger off-road tires, suspension lifts, or re-geared axles throws off your speedometer accuracy, shift points, and fuel economy. Superchips devices like the Flashcal for JT and the wireless Flashcal+ offer quick OBD-II speedometer calibration for tire sizes up to 40 inches and axle ratios up to 5.38:1. Every Gladiator kit includes the required Security Gateway (SGW) bypass module, ensuring seamless communication with your truck's onboard electronics.

Trail Management and Custom Vehicle Controls

Engineered for overland adventure and heavy hauling, Superchips software lets you manage critical truck functions on demand. Utilizing the smartphone-enabled Flashcal+ or touchscreen interfaces, drivers gain access to real-time CRAWL Screen capabilities. Control differential lockers in 2HI and 4HI, adjust TPMS tire pressure warning thresholds for low-pressure off-roading, and temporarily bump up engine idle RPM for winching. You can also customize daily settings such as Auto Start-Stop disable memory, daytime running light preferences, and reading or clearing Diagnostic Trouble Codes (DTCs).

Enhanced Towing Power and Throttle Response

Whether navigating steep trails or pulling a camper, Superchips performance products like the Pulsar and Pulsar XT deliver instant power gains and sharper throttle control for 3.6L Pentastar V6 and 3.0L EcoDiesel JT models. By connecting directly to the engine control module, inline devices optimize ignition timing and fuel delivery curves without requiring ECU unlocking. Refined automatic transmission shift mapping eliminates gear hunting on the highway, keeping your Gladiator in the heart of its powerband under heavy loads.
