But it's not quite as powerful as its factory-produced rivals.
PaxPower has revealed its new Jackal off-road packages for the Chevrolet Silverado range, including the new ZR2 Bison model. The company has applied its upgrades to the Silverado before, upping power to 443 horsepower. But now the outfit has gone further, offering upgrades that include a supercharger kit, boosting output to 650 hp and 650 lb-ft of torque.
Yes, the Ford F-150 Raptor R and Ram TRX produce over 700 ponies, but power is not everything, and that's why PaxPower has done so much more than just make the Silverado more beastly under the hood. Moreover, not everyone wants a gas-guzzling, supercharged V8, which is why the tuner offers a number of different options.
The first is the regular Jackal kit, which can be applied to any crew cab short-box Silverado trim and sees factory body panels replaced with beefier items that add a full eight inches of width to the truck. Notably, this kit still includes fender liners. If you like, an aftermarket hood or your choice of bumpers can be added, but enough of the aesthetics.
With fabricated boxed steel control arms, the track is widened by six inches, while ground clearance improves by three inches, thanks in part to 2.5-inch front coilovers and rear shocks from King Racing Shocks. Like what you'll find on other high-quality off-road builds, remote reservoirs and adjustable damping maximize capability and tuneability. Deaver progressive-rate leaf springs also help give the truck more suspension travel.
35- or 37-inch BFGoodrich tires wrapped around 17-inch off-road wheels and a Borla stainless steel dual exhaust complete the upgrades unless you want to add additional lighting, steps, a bed cover, or more accessories.
As we mentioned earlier, PaxPower will apply upgrades to any Silverado trim, but if you've got the 6.2-liter V8, the tuner will add a 3.0-liter supercharger that runs on around 7 psi of boost and adds 55% more power, giving you 650 ponies and 650 lb-ft of twist. To achieve those figures, the kit includes a new intake, a separate cooling system, and a tune to the factory ECU. Best of all, this is available with a three-year/36,000-mile warranty.
Finally, the ZR2 Jackal builds on the improved off-road prowess of the new addition to the Silverado range with custom fenders and prerunner suspension, utilizing the original Multimatic shocks and model-specific leaf springs.
This starts at $19,950, but if you wish to build from a lesser Silverado, as outlined earlier, the package starts at $24,950. As for the supercharger kit, this costs $12,450, with the optional warranty adding two grand to the figure.
With these upgrades, the Silverado does not necessarily become a direct rival to its cross-town rivals, but it certainly looks and performs in the same league.
