As the first truck developed by GM’s Performance Division, the Trailblazer SS has a towing capacity of up to 6,700 pounds with the two-wheel drive model and up to 6,500 pounds with the available all-wheel drive model. Cargo volume is 41 cubic feet (1,161 liters) behind the rear seat and 80 cubic feet (2,265 liters) with the rear seat folded.
GM Performance Vehicle Operations tuned the SS’s suspension and upgraded its brakes. It features stiffer springs, an inch lower ride height and thicker stabilizer bars, as well as standard StabiliTrak stability control. Larger 12.8-inch-diameter front brake discs are fitted, along with new twin-piston iron calipers, while the monstrous twenty-inch aluminum wheels have 255/50 V-rated tires.
The TrailBlazer SS has unique exterior styling and specific interior details, including prominent 20-inch flangeless wheels. Power is delivered by the Corvette-derived LS2 6.0L V-8, allowing for a 0-60 mph time of 5.7 seconds. A lowered ride height performance suspension is also part of the package and was fine-tuned by GM’s Performance Division at several race tracks, including Germany’s legendary Nürburgring, a challenging course featuring more than 12.5 miles of curves and drastic elevation changes. The TrailBlazer SS is available in two-wheel drive and all-wheel drive configurations.
The TrailBlazer SS’s four-wheel disc brake system is upgraded with larger 12.8-inch front disc brake rotors and new dual-piston iron calipers. Heavy-duty iron calipers are stiff and retain their shape under high-pressure/heat braking conditions, providing a linear feel and reduced pedal travel at high-energy stops. Brake pads use the same high-performance coatings as the Corvette for strong fade resistance. ABS is standard. A front brake cooling package is also available to optimize performance on the track.
Chevrolet engineers performed an extensive chassis tune-up on the Trailblazer SS, lowering the suspension 1 inch and adding 25% stiffer springs. Ride height has been lowered about an inch using 25 percent stiffer for a firmer ride and reduced body roll, and to give the TrailBlazer SS a lower, more aggressive ride.
The SS model remains distinctive with the black diamond grille, decklid spoiler, and overall looks more like the NASCAR cars from Gordon’s campaigns. It has 20-inch polished aluminum wheels and four-wheel discs (12.8-inch rotors up front). StabiliTrak and a rear air leveling suspension are also standard on the SS.
The TrailBlazer SS’s engine has a composite intake manifold used on other midsize trucks and was adapted for the LS2 to help produce balanced power and torque within package parameters. The engine also has the Trailblazer’s signature bypass oil pan. The cast pan passage allows the front differential half shaft to pass through the pan instead of under it. This helps keep the engine mounted lower in the chassis for better balance and a lower center of gravity. There’s also a stylish SS-specific engine cover, radiator support shroud and coordinated air induction box.
Backing up the 6.0L V-8 is a new 4L70-E Hydra-Matic electronically controlled four-speed automatic transmission. It makes its debut in the TrailBlazer SS and was developed to handle the high horsepower and torque loads of performance-oriented lightweight vehicles. Special high-strength, heat-treated materials are used throughout the 4L70-E to ensure it delivers smooth, dependable shifting.
