2021 Ram 1500 Hennessey TRX Mammoth 900
THIS… is a 2021 Ram 1500 TRX Hennessey Mammoth 900, finished in Granite Crystal with a matte green vinyl wrap and a black interior.
- This TRX has been fitted with Hennessey Performance’s Mammoth 900 upgrade package. Modifications include an ECU tune, a ported supercharger snout, lower and upper pulley upgrades, high-flow fuel injectors, an air intake system, and metal front and rear bumpers.
- According to the window sticker provided in the gallery, factory equipment includes the TRX Level 2 Equipment, TRX Carbon Fiber, Technology Group, Trailer-Tow Group, and Advanced Safety Group packages, an electronic locking rear differential, Mopar Off-Road Style running boards, a dual-pane sunroof, leather upholstery, TRX Red interior accents, a Harman/Kardon 19-speaker premium sound system, and more as detailed below.
- Ram took a direct shot at the Ford F-150 Raptor when it released the 1500 TRX for the 2021 model year. Developed for high-speed off-road driving, the TRX gains a strengthened frame, a long-travel suspension system, a model-specific exterior design, and Dodge’s celebrated Hellcat engine. It’s the world’s most powerful series-produced pickup.
- Power comes from a supercharged 6.2-liter Hellcat Hemi V8, rated at 702 horsepower and 650 lb-ft of torque in stock form. Hennessey claims its modifications increase those figures to 912 horsepower and 873 lb-ft of torque, but a dyno sheet was not provided to confirm. Output is sent to all four wheels via an 8-speed automatic transmission.
