Choose the Hennessey H600 Silverado when your preference is a lowered street truck; consider the Goliath 700 ZR2 when you want the listed off-road-oriented wheels, tires, suspension and bumpers. They are not the same conversion with different horsepower badges.
Our October 12, 2026 inventory review identifies 2025 Silverado RST H600 CH293662 and 2026 Silverado ZR2 Goliath 700 CH221835. The model year, base trim and conversion all differ. Compare those differences openly instead of presenting them as two identically equipped trucks.
H600: lower stance and street-focused equipment
CH293662 is listed with a supercharged 6.2-liter V8, ten-speed automatic and 4WD. Its described conversion includes 625 bhp, 611 lb-ft, a coilover lowering system, upgraded control arms, traction bars, a rear sway bar, 24-inch Hennessey wheels and street-performance tires. Hennessey's H600 Silverado package information supports that general specification.
The appeal is a coordinated sport-truck build with a visually lower profile. It deserves consideration when the truck's normal life involves paved roads and you prefer that appearance. Do not translate the package description into a promise of ride comfort or grip in every condition; assess those factors on an appropriate test drive.
Goliath 700 ZR2: a different starting platform
CH221835 is listed as a 2026 White Sands Silverado ZR2. The catalog describes a 700-bhp, 611-lb-ft supercharger package, BDS suspension upgrades with upper control arms, integrated Multimatic DSSV shocks, 20-inch off-road wheels and 35-inch tires. It also identifies steel front and rear Goliath bumpers, a skid plate, lighting, power running boards and carbon-fiber trim.
Hennessey's 2026 ZR2 release establishes the named package. The truck's final equipment records determine the specific example. We are not applying the manufacturer's acceleration test to this stock number or claiming a higher towing rating from its engine output.
Decide what changes your everyday ownership
Start with clearance and access. Measure the H600 against driveway ramps and the Goliath against garage height. Try the entry steps and check how the altered front end affects your view. Use actual measurements rather than adding an advertised lift or lowering amount to a generic factory dimension.
Then compare the tires as an ownership expense. The 24-inch street wheel/tire package and the 20-inch off-road wheel with 35-inch tires solve different preferences. Get replacement quotes, inspect the installed load specifications and decide how much of your driving genuinely needs an off-road tire.
Finally, compare the cabins. RST and ZR2 start with different equipment possibilities, and the conversions can add more. Check the actual seat materials, displays, cameras and audio equipment instead of assuming the less expensive base trim has the same features after customization.
Make the purchase comparison complete
Ask for both VINs' current written quotes, build records, fuel requirements and coverage documents. Identify who services each added component. Review rated payload, axle, tire and hitch limits independently of the horsepower comparison.
The right purchase is the truck whose included equipment you would choose and use. A stock Silverado remains worth comparing when neither complete conversion matches your routine.
Does H600 mean exactly 600 horsepower?
No. The package referenced here is advertised at 625 bhp. Use the documented package specification, not arithmetic inferred from its name.
Is Goliath simply an H600 with bigger tires?
No. These examples have different base trims, model years, chassis equipment and stated power packages.
