Renowned performance tuning company, Callaway, must have a lot of cargo to haul around these days. First, it teased us with the Corvette Stingray Shooting Brake back in March, and now it is getting to work on the all-new 2014 Chevrolet Silverado and GMC Sierra trucks.

With all-new EcoTec3 V8 engines featuring direct injection and variable valve timing, Callaway is looking to use supercharging to bump the 5.3-liter V8 up to 450 horsepower and the 6.2-liter V8 up to 540 hp – increases of 95 hp and 120 hp, respectively. These Supercharged SportTrucks will be introduced later this year, as will other performance products such as air intake and exhaust system upgrades.

The only visual changes we see from the single image released (click to expand) include Callaway badges on the doors and grille, as well as nine-spoke alloy wheels, which appear to be the same found on the company's Silverado-based C19 SportTruck. No word yet on pricing, but as reference, the current Callaway SportTruck upgrades start at $17,395 not including the alloy wheels or the suspension and brake mods.

2014 CALLAWAY SILVERADO AND SIERRA DEVELOPMENT - IN PROCESS

OLD LYME, CONNECTICUT (July 02, 2013)–

Callaway engineers are hard at work developing the company's latest Supercharged versions of 2014 GM SportTrucks, after receiving their first 2014 Chevrolet Silverado and GMC Sierra trucks this past week.

2014 Silverado and Sierra product development, testing and validation will be conducted over the next few months. Supercharged 5.3L and 6.2L models are projected to be available later this year, in every GM-built cab and bed combination. Expect premium performance, quality and value consistent with other Callaway car and truck packages.

Through the application of Callaway's proven supercharging techniques, Callaway expects to exceed 450 horsepower for the 5.3L configuration and to generate more than 540 horsepower in the 6.2L offering. With the new 5.3L and 6.2L EcoTec3 engines incorporating such technological advances as direct injection and variable valve timing, Callaway engineers now have even greater control of engine operating parameters. These features provide additional tools for improved compatibility with supercharging's positive manifold pressure, as well as a clearer path for 50-state emissions compliance and extended durability.

Wheel, tire, suspension, interior and body upgrade development is well under-way, with these options being made available coincident with Callaway Supercharged SportTruck launches later this year.
Callaway Supercharged versions of 2014 Tahoe, Suburban, Yukon, Denali and Escalade are available now, as these models remain largely unchanged for 2014.

Other Callaway products in development for GM's latest truck and SUV offerings include a specific version of their legendary Honker air intake and DD exhaust systems. These products are being made available for the first time as stand alone components, to be installed by the consumer or Authorized Callaway Retailer, on otherwise stock GM trucks and SUVs.

All Callaway vehicle packages and products are made available through an exclusive network of Callaway Authorized Retailers. Please visit callawaycars.com for further information.

      Why does a truck have little thin sport car tires? Just looks... Odd.

      Who cares? It's a General Motors product. It's junk before it rolls off the assembly line. And then Callaway will make it that much worse.

      That is one ugly truck. It looks like something from the 80's.

        not a all the same type of truck, the raptor is a rally truck, this is a street truck.

      Adding the breathing of overhead cams and four valves/cylinder would give them even more power. Engine physical size isn't a factor in a truck. How 'bout it?

      Fairly useless. Even with stock 400+hp the rear wheels spin....a LOT. With 4WD, not so much. Until the drivetrain blows..

        apparently you have never seen any youtube videos of 1000 hp 9 and 10 sec 2wd and 4wd chevy trucks. Look it up

        They don't spin much at all, and actually genius, you mean AWD. Nice try.

      Improved horsepower / durability / passing emissions is great but what are the fuel economy numbers on these vehicles ? Have Miles per Gallon been improved or are the numbers worse ? Even if you want a truck with huge amounts of power, I would still think MPGs are a concern unless you are that money guy that rides around in boats or motorcycles as the bills fly away !

        @al4gg10
        if you're spending 17grand to get supercharged and for more power, fuel economy is at the bottom of your list of concerns

      Wheels look tacky. There is more than enough shiny chrome on the front of the truck. It's not just a Silverado issue, pretty much all of the fullsize and HD trucks (with a few exceptions) are just loaded to the gills with awful chrome everywhere.

      Graphics and body kits are kind of lame -- but if I'm paying $17k for something like this, I'd like to think the truck would be a little more distinguished. I know they did the badges and the wheels but still 95% of people would never notice. Also, I don't think 540hp is too impressive from the 6.2L since GM and others have gotten much higher numbers from a supercharger.
