The new record, which was verified by Guinness World Records, edges out the previous high water mark set in 2012 of 155.78km/h (96.8mph).
In this era of 400km/h-plus hypercars, falling just shy of 160km/h doesn't seem like a particularly noteworthy achievement until one factors in just how much monster trucks weigh.
Measuring three metres tall and 3.8 metres wide, the Raminator tips the scales at over 4670 kilograms. The Raminator is powered by a supercharged 9.3-litre Hemi V8 engine, which is said to develop over 1491kW (2000hp) of power.
The Raminator uses a custom tubular racing chassis. Attached to the car's four-link suspension and nitro gas shock absorbers are massive grooved tyres measuring 66-inch by 43-inch by 25-inch (1.68m by 1.1m by 63cm).
Atop the monster truck's massive tyres, the Raminator wears a body shell similar to the Ram 1500 pickup truck.
To put the Raminator into perspective, the largest Ram 1500 available in showrooms today is just two metres wide, two metres tall and weighs a mere 2470kg. The range-topping 295kW 5.7-litre Hemi V8 also seems a little underpowered in comparison.
