17 May MAMMOTH 1000 TRX Test Drive with John Hennessey
MAMMOTH 1000 TRX Test Drive with John Hennessey!
John Hennessey gives his driving impression of the new Hennessey MAMMOTH 1000 truck. For some of us, 702 HP simply isn’t enough for our supercharged 6.2L Hellcat-powered RAM TRX. Hennessey has the solution in the form of 900 and 1000 HP upgrades. Every upgrade is expertly installed, diligently calibrated, and supported by a warranty and world-class customer service.
