Take control of your late-model 2022.5–2026 Silverado or Sierra 1500 with Range Technology. Our updated AFM/DFM and Start/Stop Disablers are fully compatible with GM’s latest ECM systems, providing seamless full-time V8 power, better towing response, and increased drivability—all in a simple plug-and-play module.

Run all cylinders, all the time. The Range AFM/DFM Disabler keeps your GM V6 or V8 in full power mode, blocking Active and Dynamic Fuel Management without touching your ECU.
