GMC offers off-road-ready versions of the Sierra 1500 in the form of the AT4 and AT4X, but for those seeking even more capability, Texas-based aftermarket company PaxPower has a solution. The PaxPower Jackal package is designed to further upgrade the off-road capability of mid-2022-2024 GMC Sierra 1500 pickups by adding long-travel suspension, widened bodywork, and a supercharger option to the donor trucks.
The package is available for any Sierra trim level with a crew cab and short bed. One of the key upgrades is the addition of new fenders that widen the truck by 8.0 inches. These wider fenders allow for the fitment of larger 35-inch or 37-inch BFGoodrich tires, mounted on 17-inch wheels. Additionally, customers have the option to further modify the exterior with aftermarket hoods and off-road bumpers.
The suspension modifications are crucial for improved off-road performance. The revised suspension includes boxed steel control arms that increase track width by 6.0 inches, provide 3.0 inches of additional ground clearance, and offer more suspension travel. According to PaxPower, the front suspension utilizes 2.5-inch coilovers, while the rear suspension features progressive leaf springs. Furthermore, both front and rear remote-reservoir King Racing Shocks are included in the package. Builds based on the Sierra AT4X use the Multimatic DSSV dampers and model-specific leaf springs that come standard with that version.
In terms of powertrain, PaxPower offers modifications for the 5.3-liter and 6.2-liter gasoline V-8s, as well as the 3.0-liter turbodiesel inline-6. However, the 2.7-liter gasoline turbo-4 is not compatible with the package. For the 6.2-liter V-8, PaxPower adds a 3.0-liter Whipple supercharger and a higher-flow air intake, boosting the output from the stock 420 horsepower and 460 lb-ft of torque to an impressive 650 horsepower and 650 lb-ft of torque.

The pricing for the PaxPower Jackal package varies depending on the model. For most Sierra models, the package starts at $25,950. However, for AT4X models, the price is lower at $19,950 since PaxPower is able to reuse more of the stock suspension components. It’s important to note that these prices do not include the cost of the donor truck, which must be sourced from a GMC dealer. PaxPower also offers similar upgrades for the Chevrolet Silverado 1500, which shares its platform with the GMC Sierra.
Overall, the PaxPower Jackal package provides GMC Sierra 1500 owners with even greater off-road capability. With its upgraded suspension, widened bodywork, and optional supercharger, the Jackal package allows these pickups to tackle more challenging terrains and provide an exhilarating driving experience. Whether you’re passionate about off-roading or simply looking for a unique and capable truck, the PaxPower Jackal is certainly a compelling option to consider.
