Callaway Introduces 520 HP And 602 HP Upgrade Kits For 2021-2022 General Motors Vehicles
by AutoExpert | 4 August, 2022
The latest pickup trucks and SUV vehicles from General Motors are now compatible with a new line of upgrade kits that have just been introduced by Callaway. The company's GenThree supercharging systems, which combine high displacement Eaton TVS rotor pack components with Callaway's own supercharger casing and intercooler system, are used in all enhanced editions.
For the 2021–2022 models, the company has also created new intake and exhaust systems, resulting in GM's 5.3–liter V8 engines producing 520 horsepower, while the 6.2–liter V8 engines can now produce 602 horsepower.
The 2022–2023 Silverado SC520 and SC602 are part of the revised Callaway lineup, along with the 2022–2023 Sierra SC520 and SC602, the 2021–2023 Suburban SC520 and SC602, the 2021–2023 Tahoe SC520 and SC602, the 2021–2023 Yukon/Yukon XL SC520 and Yukon/Yukon XL SC602, and the 2021–2023 Escalade SC.
Each model has a different set of standard and optional components, but all include the full supercharging kit, aluminum door sill inserts, Callaway key medallions, chrome exterior Callaway badging, a dash-mounted authentication plaque, a build authentication plaque under the hood, and an Authenticity Documentation Package from Callaway as standard equipment.
Even while Callaway's upgrade kits can produce up to 182 horsepower and 100 lb-ft more torque than the base GM versions, "fuel consumption is nearly unchanged from stock," the company claims. All of these improved Callaway vehicles from 2021 through 2023 have electronic powertrain calibrations and engine control parts that are 50-state emissions compliant, and they all have limited warranties of three years or 36,000 miles.
