Hennessey Performance has unleashed the Goliath 700 ZR2, a dramatically upgraded Chevrolet Silverado ZR2 pickup that delivers supercar-level acceleration alongside uncompromising off-road capability. This isn’t just about horsepower; it’s about turning a rugged truck into a high-performance machine without sacrificing usability.
The Core Upgrade: A Twin-Screw Supercharger
The heart of the Goliath 700 is a massive power boost achieved through a twin-screw supercharger fitted to the Silverado ZR2’s 6.2-liter V8 engine. This transforms the truck’s output from the standard 420 hp and 460 lb-ft of torque to a staggering 700 hp and 611 lb-ft. The result? A 0-to-60 mph time of just 4.2 seconds – a full 1.4 seconds quicker than the stock ZR2.
This kind of performance from a pickup is unusual. Most trucks prioritize towing and hauling over raw speed, but Hennessey has bridged that gap. The Goliath 700 shows how serious power can be paired with the ruggedness of the ZR2 platform.
Beyond the Engine: Suspension, Wheels, and Styling
The upgrades don’t stop at the engine bay. Hennessey has refined the ZR2’s already capable suspension with BDS components and Multimatic DSSV shocks to enhance stability and control, both on and off-road. The truck also receives:
- New upper control arms
- 20-inch off-road wheels wrapped in 35-inch tires
- A custom stainless steel catback exhaust with black tips
- A steel front bumper with a 40-inch LED light bar
- Steel rear bumper and electronic power running boards
These changes aren’t just for show. They’re designed to make the Goliath 700 as capable in the dirt as it is on the pavement. The exterior is now aggressively styled to match its performance.
The Result: Extreme Power, Refined Capability
According to Hennessey President Alex Roys, the Goliath 700 ZR2 is for “customers who want extreme power and capability without compromising on usability and comfort.” The modifications create a truck that is equally at home on a highway or challenging terrain.
“We’ve created a truck with purpose that feels just as confident on the highway as it does tackling challenging terrain.”
The Goliath 700 ZR2 represents a unique combination of brute force and refined performance. It’s a reminder that trucks don’t have to be slow, and that capability can be taken to extremes without sacrificing everyday usability.
