The Ram 1500 TRX is an impressive machine in its own right. With a 6.2-liter supercharged Hellcat V8 pumping out 702 hp and 650 lb-ft of torque, this full-size truck has numbers that wouldn’t look out of place attached to a Supercar’s spec sheet. It can even out-accelerate many sports cars while offering an immensely capable off-road experience, with seemingly nothing able to get in its way. But that, of course, is a stock Ram 1500 TRX. And when it comes to the folks at Hennessey Performance, stock just doesn’t cut it. Which is why the 2021 Ram 1500 TRX Hennessey, with the Mammoth 900 upgrade package, is anything but stock. With some specialty modifications made, this already power-packed truck now sends over 900 hp to the four wheels. This limited-edition truck could be yours with just over 11,000 miles on the clock.
Exterior and Interior
While the power plant is undoubtedly a massive draw for this 2021 Ram 1500 TRX Hennessey Mammoth 900, the team at Hennessey Performance also pays attention to the interior and exterior. This Ram TRX is finished in Diamond Black Crystal Pearl Coat Exterior Paint and includes the TRX Carbon Fiber Exterior Package. Moving to the rear, you’ll find that the bed utility group has been spec’d, too, and a divider rail system. The exterior is further finished off with off-road-style running boards by Mopar and subtle but purposeful Mammoth 900 exterior badges and Hennessy exterior badging. Move inside the 2021 Ram 1500 TRX Hennessey Mammoth 900, and you’ll find a luxurious interior with black leather seats and carbon fiber accents. The truck features a remote start system, as well as a Harmon Kardon surround sound audio system.
Engine
Under the hood, the 2021 Ram 1500 TRX Hennessey Mammoth 900 features a 6.2-liter supercharged V8 engine that has been extensively modified by Hennessey Performance. The tuning includes the installation of a lower pulley and upper pulley upgrade, a ported supercharger inlet, high-flow fuel injectors, a high-flow air induction and crank-case ventilation system, and tweaking the ECU. The truck has been dyno-tuned, and Hennessey rates the Mammoth 900 to produce 912 hp and 873 lb-ft of torque at the crank. The Mammoth 900 also features a Hennessey exhaust system and high-performance brakes.
Inspection
