Performance Modules

From a new transmission and suspension to a revamped exhaust system, dedicated jeepers are always seeking ways to push their rigs even further and get even more performance. Mechanical modifications aren't the end of it, though - with more sophisticated computer systems in cars and trucks these days, the key to breaking your Jeep's limits can be found in upgrading your onboard electronics. For this, 4WheelParts.com offers aftermarket performance modules for sale, redefining what your rig is capable of. Greater fuel mileage, clean emissions and higher power output are just a few of the ways a new performance module raises your Jeep's potential.

Go Further Than Ever Before

Your vehicle houses an engine control unit (ECU) that manages the engine's ignition and fuel systems, from the fuel/air mixture to the spark and cylinder timings. Truck performance modules adjust the built-in factory values that define the engine's usual functioning. By fine-tuning this information and the ECU's guidance, a performance module can optimize your engine's capabilities or even - for ATV racers and the biggest thrill-seekers - push them beyond factory limits on demand. Aftermarket brands from aFe Power to Jet Performance Products offer the top performance modules, designed for direct fit in most years, makes and models and serving needs from basic improvements to full-throttle power.
