MAMMOTH 6X6

The Hennessey MAMMOTH 6X6 is the ultimate Ram TRX in the most American way possible: bigger, longer, taller, more power, more noise and plenty more of everything! Hennessey has significantly extended the TRX platform and added a third axle and a gigantic flatbed at the rear.

Additional third axel completes the 6X6 setup of this behemoth.

UPGRADED SUSPENSION

Upgraded Bilstein Suspension for the most luxurious of rides in such an absurd ride.
