>> Available ‘GOLIATH OFF-ROAD’ package for GMC Sierra AT4 adds aggressive custom steel bumpers, LED light bar and driving lamps, and Hennessey 20-inch aluminum wheels with 35-inch off-road tires

Sealy, Texas (December 12, 2023) – Hennessey, the Texas-based hypercar manufacturer and high-performance vehicle creator, has announced comprehensive upgrades for General Motors pickup trucks with its ‘GOLIATH 650’ build. The new supercharged performance upgrade delivers an impressive 55 percent increase in horsepower and a 43 percent increase in torque — a warranty backs the upgrade.

The factory Chevrolet Silverado and GMC Sierra pickups may be optioned with GM’s naturally aspirated 6.2-liter V8 — the powerplant is the largest and most potent naturally aspirated gasoline-fed eight-cylinder in its class. Stock output is 420 horsepower and 460 lb-ft of torque, sending power through GM’s Hydra-Matic 10-speed automatic transmission with part- or full-time four-wheel drive.

Obsessed with ‘making fast cars faster’ since 1991 and determined to release the full potential of the GM’s engine, the engineers at Hennessey upgrade the Sierra and Silverado’s 6.2-liter V8 (L87 EcoTec3) with a robust 3.0-liter supercharger, high-flow intake system, high-flow intercooler, and a crankcase ventilation system. In addition, chromoly pushrods are installed, and the engine management software is enhanced with HPE engine management calibration. Lastly, a stainless-steel cat-back exhaust system (retaining stock exhaust tips) is installed to improve performance and soundtrack. The result is a dyno-proven 650 bhp and 658 lb-ft of torque.

The ‘GOLIATH OFF-ROAD’ package complements the supercharged power upgrade on the GMC Sierra AT4 and adds a custom front steel bumper with ‘GOLIATH’ laser-etched into the plate. An LED lightbar and LED driving lamps are also installed to enhance visibility on- and off-road while further boosting the vehicle’s presence. The chassis is lifted with an off-road suspension upgrade, and Hennessey 20-inch aluminum wheels, with rugged 35-inch off-road tires, replace the stock 18-inch wheels.
