The 2024 RAM 1500 TRX Hennessey Mammoth 1000 Last Stand is the kind of truck that feels like the end of an era, built around a supercharged HEMI V8 and then turned into a four-digit-horsepower Hennessey supertruck. Showing 26,816 miles, this Bright White over Black TRX comes equipped with Customer Preferred Package 29Y, Advanced Safety Group, Bed Utility Group, TRX Level 2 Equipment Group, dual-pane panoramic sunroof, Mopar TRX hood graphics, Mopar off-road style running boards, and lower two-tone paint. The Hennessey Mammoth 1000 Last Stand Package is what makes it special, bringing 1000 BHP, 969 lb-ft of torque, upgraded high-flow supercharger hardware, HPE ECM and TCM calibration upgrades, Mammoth custom bumpers, 20-inch Hennessey wheels, 35-inch off-road tires, Last Stand graphics, Hennessey badging, and limited-edition 1 of 200 status to one of the wildest factory truck platforms of the modern era.
The 2022 RAM 1500 TRX Ignition Edition is one of the most exclusive versions of RAM’s halo performance truck, combining factory-limited production with relentless supercharged V8 power and premium appointments. Finished in the unmistakable Ignition Orange Clear-Coat, the Ignition Edition stands apart with unique styling cues and a host of upscale features from the factory. Showing just 13,027 miles, this example has been tastefully transformed with an aftermarket leveling kit, massive 22-inch JTX forged wheels wrapped in 37-inch Toyo tires, paint-matched exterior trim, custom lighting, rock lights, AMP Research power-deployable running boards, and custom exterior emblems, giving this already imposing truck an even more commanding presence.
Factory trucks have become faster and more refined than ever, but few receive the kind of transformation that turns them into a true head-turner. This 2025 RAM 1500 Big Horn Black Widow is one of those trucks. Built by Black Widow and based on the redesigned fifth-generation RAM 1500, it combines the all-new Hurricane twin-turbocharged inline-six with an aggressive lifted stance, premium styling upgrades, and enhanced off-road capability. Showing just 11,931 miles, this example is loaded with desirable factory equipment including the Night Edition, Big Horn Level 2 Equipment Group, Bed Utility Group, and a dual-pane panoramic sunroof, then elevated even further with the complete Black Widow Package. Whether it’s pulling into a truck meet, tackling weekend trails, or serving as a luxurious daily driver, this RAM delivers a presence few pickups can match.
