This is available on mid-2022 to 2024 Sierras.

Locally, the off-road or performance full-size SUV category is dominated by the likes of theFord F-150 Raptorand the RAM 1500 TRX. TheGMC Sierramay not be the top dog for the said market for now, but PaxPower may have something that could change that.

The truck tuner company has rolled out its Jackal off-road packages for the Sierra, particularly on any crew-cab short-box trims of the mid-2022 to 2024 model years. This package offers a more rugged appearance and improvements in the powertrain department.

But first, let's talk about the cosmetic changes PaxPower made for the GMC Sierra.

PaxPower

The company installs a body kit eight inches wider than the stock. The equipment can be complemented by several options for aftermarket hoods and off-road bumpers, giving the truck a sturdier stance.

The upgraded GMC truck can match the looks of thef - 150“猛禽”with the PaxPower package. Yes, the tuning company worked on the Blue Oval brand's full-size pickup truck last year, tuned to deliver as much as 770 horsepower.

Meanwhile, the PaxPower Jackal Sierra has been tuned to make 650 hp and 650 lb-ft of torque - way morepowerful than the Sierra AT4X. The power bump was made possible by adding a 3.0-liter supercharger to the 6.2-liter V8 EcoTec3 engine, increasing the power by 55%. The supercharger system also has a high-flow air intake, a separate cooling system, and around seven psi of boost.

Models powered by the 5.3-liter EcoTec3 V8 and 3.0-liter Duramax engines are also available with PaxPower packages. These powertrain upgrades are also found in thePaxPower Jackal Silverado, released earlier this year.

Other bits included in the package are fabricated boxed steel control arms that widen the track by six inches and provide three inches of lift, 2.5-inch front coilovers, rear shocks from King Racing Shocks, upgraded leaf springs for the rear, and a choice of either 35 or 37-inch BFGoodrich tires.

For $25,950, the complete Jackal package transforms the Sierra into a more off-road-ready pickup capable of putting up a good fight against the formidable Blue Oval rival.
