Any Ram pickup is an impressive machine, but the work carried out on this 2021 Ram 1500 Hennessey Mammoth 900 TRX could well blow your mind. Despite claiming to have nearly 1,000 horsepower under the hood, the exterior of this pickup doesn't shout about it. In many ways, the black-on-black exterior exudes stealth. However, this Ram 1500 remains subtly purposeful — even to the casual observer. It features functional upgrades such as custom front and rear bumpers, larger wheel and tires, and badging from Hennessey Performance and Mammoth Offroad. If that wasn't enough incentive, this Ram has just 4,350 miles on the odometer. That makes this pickup barely run in — in fact, it's still within the three-year or 36,000-mile warranty.
Exterior and Interior
This 2021 Ram 1500 Hennessey Mammoth 900 TRX is finished in the Diamond Black Crystal Pearl-Coat paint. The Mammoth 900 upgrade by Hennessey includes a Mammoth custom front bumper with embedded LED lights, Mammoth custom rear bumper, Hennessey & Mammoth exterior badging, and of course, 20-inch Hennessey 10-spoke wheels painted in black. Added to the TRX is the TRX carbon-fiber package, bed utility group, trailer-tow group, and the technology group. Access to the interior is aided via upgraded electronic fold-out steps. The interior is upholstered with Hennessey embroidered headrests and a dual-pane panoramic sunroof. Entertainment is provided through a 19-speaker Harman Kardon premium sound experience. The Hennessey treatment adds a unique serial numbered engine bay plaque.

The Mammoth Off-Road Stage 2 kit on this 2021 RAM 1500 Hennessey Mammoth 900 TRX adds a front leveling kit.

In short, these upgrades translate to a claimed 912hp of power and 873 lb. ft of earth crushing torque. Any terrain can be tackled by the 37" TOYO R/T off-road wheels.
