Hennessey says the new package can be equipped to any 2021-2023 Mammoth TRX model, including the Mammoth 900 and Mammoth 1000 versions. As a reminder, the Mammoth 900 develops 912 horsepower from its tuned 6.2-liter Supercharged Hemi V8, and the Mammoth 1000 delivers 1,012 hp and 969 lb-ft torque. The carbon kit costs $11,950 and includes a three-year/36,000-mile limited warranty.
That price does not include the actual Ram TRX, which starts at $84,555 before options and delivery. Then there’s the Mammoth upgrade package from Hennessey, which brings the total price to around $150,000 before additional extras like the available Overlanding kit for $20,000.
