Chevy Silverado & GMC Sierra with Hennessey`s Goliath 650 Upgrade Kit

Introducing the Mighty Goliath 650 Beast

Hennessey, the well-known Texas customizer is making waves again with their latest project called the Goliath 650, a tuning package carried out for the Chevrolet Silverado and GMC Sierra. While it may not boast the 6×6 conversions seen on other trucks, Hennessey’s enhancements seen here are undeniably impressive and give these American pickups a substantial performance upgrade.

Thrilling Power Enhancements

The Goliath 650 package is specifically designed for the shared 6.2 liter L87 EcoTec3 V8 engine found in both the Silverado and Sierra. Hennessey began the modifications by equipping a 3.0-liter supercharger, which is a game-changing addition that sets the stage for power. Additional modifications include a high-flow intake system, an upgraded intercooler, and an enhanced crankcase ventilation system.

Hennessey didn`t stop there with their expertise and additionally installed pushrods and optimized engine software for peak performance. They also fitted a stainless-steel cat-back exhaust system and retained the exhaust tips to preserve the truck’s original appearance while delivering a satisfying V8 soundtrack. All of these changes culminate in an output of 650 horsepower and 658 lb-ft (892 NM) of torque.

Models Enhanced by the Goliath 650

The Goliath 650 upgrade is not limited to one trim level; it caters to a variety of models ensuring that both Silverado and Sierra enthusiasts can enjoy the thrill of improved performance.

Off-Road Capability with an AT4 Upgrade

For those who own a GMC Sierra AT4 and crave off-road capability, Hennessey offers a unique off-road package. This package is specifically designed to enhance the spirit of the Sierra AT4. It includes a custom steel bumper featuring laser etched ‘Goliath’ lettering that adds a touch of style. Additionally, it comes with an LED lightbar LED driving lights, 20-inch Hennessey wheels paired with durable 35-inch off-road tires, and a suspension lift to complete the ultimate off-road ensemble.
