Overview

The Range RA003B is an AFM/DFM Disabler designed for GM vehicles. This device disables GM's Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems, allowing your engine to operate in full cylinder mode consistently. It eliminates transitions between V4 and V8 operation, providing smooth, consistent power.

Installation is plug-and-play via the OBD-II port, with no tools or permanent modifications required. The disabler does not reprogram the factory ECU and can be unplugged to return the vehicle to stock operation. It features built-in power management to prevent battery drain and is compatible with a wide range of GM trucks, SUVs, and cars from 2007-2022.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
