Range Technology, part of the Holley Performance Brands portfolio, has announced expanded compatibility for the RA007 Active Fuel Management Disable Module, now supporting 2026 GM Refresh Silverado and Sierra 1500 models equipped with 5.3L and 6.2L V8 engines. Engineered for performance enthusiasts, towing professionals, and installation shops, the RA007 delivers the full-time V8 power and reliability that modern GM truck owners demand—now extended through the newest model year.
“The RA007 has earned its reputation as the simplest, safest path to real V8 performance,” said Mike Litsch, Senior Product Manager at Range Technology. “With our expanded 2026 compatibility, we’re reaffirming our commitment to the modern GM truck community—delivering plug-and-play reliability with zero trace and full warranty confidence.”
The RA007 eliminates both Dynamic Fuel Management (DFM) and Auto Start/Stop functions, ensuring consistent eight-cylinder operation for a smoother, stronger driving experience. With the latest firmware update, the RA007 now supports GM’s advanced Global B electrical architecture, making it the first-to-market plug-and-play solution specifically engineered for the newest generation of GM trucks. Installation is simple and fully reversible. The RA007 connects inline at the ECM, requiring no tuning or ECU flashing and leaving no digital footprint. This design allows owners to enjoy full-time V8 power while maintaining complete factory warranty integrity, an especially important feature for new truck owners and dealerships alike.
Behind the scenes, Range Technology’s engineering team validated the RA007 through more than 8,000 hours of lab and road testing and over 100,000 miles of real-world use. “We don’t just engineer for specs—we test for life,” Litsch added. “That means miles on the road, heavy towing, stop-and-go traffic, and mountain climbs. Our modules prove themselves where enthusiasts use them most.” The result is a product that enhances drivability, improves throttle response, and reduces wear on engine components by eliminating constant mode switching. With its refined calibration and seamless integration, the RA007 provides a more enjoyable and durable driving experience—ideal for towing, daily use, or spirited driving.
In addition to its performance benefits, the RA007 is EPA compliant in 49 states and is currently undergoing review for CARB approval to ensure legality across all 50 states. This makes it a trusted choice for enthusiasts and professionals who value both performance and compliance.
The Range Technology RA007 DFM Disable Module is available now at RangeTechnology.com and through authorized automotive performance retailers nationwide.
