650-HP PaxPower Jackal Is The Chevrolet Silverado's Answer To Raptor And TRX

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.
