Hennessey recently sent a MAMMOTH 1000-upgraded RAM TRX, a VelociRaptor 600-upgraded Ford Raptor, and a VelociRaptor 400-upgraded Ford Bronco to California's Glamis Dunes for a series of off road torture tests to the vehicles and their modifications. Step behind the scenes with technician James, who was responsible for keeping everything running correctly over the two days of testing.

Hennessey trusts Pennzoil lubricants to provide optimal performance and reliability. The Proof is in The Pennzoil!
