TrailBlazer SS details

TrailBlazer SS 2007 is a serious performer and a capable midsize SUV. Riding on a 1-inch-lower suspension, the TrailBlazer SS's suspension was tuned and tested on the racetrack to deliver responsive, balanced handling. The lower ride height reduces the vehicle's center of gravity, improving overall handling. This was accomplished with new springs at all four corners. The springs are up to 25 percent stiffer, which complements the lowered ride height with a firmer feel and reduced body roll. Corner control and body roll control also are improved with front stabilizer bars that are approximately 10 percent larger in diameter than other TrailBlazer models. StabiliTrak electronic stability control is standard.

The four-wheel disc braking system of the TrailBlazer SS 2007 is enhanced with larger, 12.8-inch front disc brake rotors and iron twin-piston calipers. The heavy-duty iron calipers are stiff and retain their shape under high pressure/high heat braking conditions, providing a more linear feel and reduced pedal travel in high-energy stops. The brake pads use the same high-performance linings as the Corvette for strong fade resistance. ABS is standard. There also is an accessory front brake cooling package available for optimized track performance. With TrailBlazer SS's brakes, tires and revised ABS algorithm, 62 mph to 0 (100 kph to 0) stopping distance is approximately 135 feet.

Under the hood of the TrailBlazer SS 2007 is the LS2 6.0L V-8. It is rated at 395 horsepower (295 kW) and 400 lb.-ft. of torque (542 Nm). The LS2 6.0L is based on the Gen IV small-block V-8 architecture and delivers satisfying down-low torque for strong off-the-line performance. Torque is inherent to the engine's cam-in-block design, large 4.00-inch-diameter (101.6 mm) bores and 3.62-inch (92 mm) stroke. Response is crisp and immediate, thanks to the electronically controlled throttle.

Unique to the TrailBlazer SS's version of the engine is a composite intake manifold used in other midsize trucks and adapted to the LS2 to help produce balanced torque and horsepower within packaging parameters. The engine also has the TrailBlazer's trademark pass-through oil pan. The pan's cast-in passage allows the front differential's half-shaft to run 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 also is a stylish SS-specific engine cover, radiator support cover and coordinated air induction box.

Backing the 6.0L V-8 is a new Hydra-Matic 4L70 electronically controlled four-speed automatic transmission. It debuts in the TrailBlazer SS and was developed to handle the high horsepower and high torque loads of performance-oriented light-duty vehicles.
