Unleashing the Beast: Hennessey's Final 200 Tribute to the Hellcat-Powered Ram TRX
The curtain is closing on one of the most exhilarating chapters in high-performance pickup trucks, but not before one final, earth-shattering roar. With the 2024 model marking the end of the Hellcat-powered Ram 1500 TRX's reign, Hennessey Performance Engineering is sending it off with a bang. Welcome to the Hennessey Mammoth 1000 Last Stand—a monument to excess, power, and the spirit of the American V8. What could possibly make a truck that already boasts a substantial 702 horsepower and 650 pound-feet of torque insufficient? The answer lies in this limited, 200-unit special edition that turns the dials up to eleven.
The Birth of a Legend
Originating in 2021 with a starting price tag of $135,350—vehicle included—the Mammoth 1000 package quickly made headlines. It didn't simply add power; it transformed the Ram 1500 TRX into something entirely new. As we approach the final year of the 6.2-liter Hellcat and 5.7-liter HEMI engines within Ram's lineup, the Mammoth 1000 Last Stand emerges not just as a truck but as a statement—a farewell to a beloved breed.
What Sets It Apart?
Beyond the horsepower, it's the details that distinguish the Last Stand. Decals and bespoke Hennessey graphics add a layer of exclusivity, underscored by the audacious rear graphical treatments. While pricing remains under wraps, it's clear this masterpiece far exceeds the original's price point. Available in seven captivating colors—including three new hues exclusive to this edition—the Last Stand is as visually striking as it is powerful.
Under the Hood
More than just a batch of aesthetic updates, the Mammoth 1000 boasts an array of performance enhancements. A hefty supercharger, reinforced supercharger belt, and meticulously tuned engine and transmission control modules ensure unmatched power and responsiveness. The attention to detail extends to the crankcase ventilation system and the inclusion of high-performance spark plugs and a custom thermostat, all backed by a three-year/36,000-mile warranty.
More Than Muscle
Each unit undergoes extensive dyno and road testing, ensuring perfection in every aspect. For those seeking the ultimate off-road experience, Hennessey offers the optional Mammoth Off-Road Package. This adds a suite of enhancements from leveling kits and oversized tires to custom bumpers and advanced lighting solutions, cementing its status as a trail dominator. With a power output that makes the standard TRX's numbers seem quaint—1,012 horsepower and 969 pound-feet of torque—upgraded transmission and braking systems are more than mere options; they're necessities.
A Bittersweet Farewell
The departure of the Hellcat-powered Ram 1500 TRX is a poignant moment for enthusiasts. Its rival manufacturers continue to churn out V8-powered behemoths, but Ram is taking a different path. The 2025 Ram 1500 will feature a twin-turbocharged six-cylinder engine, offering a different flavor of power and performance. While the era of the Hellcat TRX comes to a close, the legacy of power and innovation it leaves behind will not be forgotten. The Hennessey Mammoth 1000 Last Stand is a fitting tribute to this legendary truck, a final celebration of all that makes the American V8 truly exceptional.
