chevy Trailblazer Used Parts Online

The Chevrolet TrailBlazer is a mid-size SUV produced by the Chevrolet division of American automaker General Motors. It was introduced in 1999 as an upscale trim line of the Blazer. In 2002, the TrailBlazer was upgraded to a new platform (GMT360 for 5 passenger models, GMT370 for 7 passenger, and GMT305 for the Envoy XUV). Production of the Blazer overlapped with the TrailBlazer until 2005, when the 2-door was sold at dealers while the 4-door was fleet only (until the 2004 model year). The TrailBlazer is based on a truck platform, with all models having four-wheel drive as an option with both automatic engagement and the more traditional "4 High" and "4 Low" gearings. Its main disadvantages are: Its increased width (as compared to, for example, a Jeep Wrangler) Lack of suspension travel due to having an independent front suspension instead of a solid axle, Tendency to high side when it encounters high-camber-variance terrain or large rocks. Absence of both locking hubs and a limited slip differential. Instead a G80 locking rear differential is available as an option on all models except for the SS which has a G86 LSD standard. The TrailBlazer was facelifted for 2006. A new front fascia and interior trim were included with the refresh, but only apply to the upper-level LT models. The LS trim still has the 02-05 front and rear fascias. The SS gets trim-specific front and rear fascias plus colormatched side skirts. The TrailBlazer comes with a 291 hp (217 kW) 277 lb-ft (376 N-m) all-aluminum 4.2 L "Atlas" LL8 inline-six engine standard and an optional 302 hp (225 kW) 330 lb-ft (447 N-m) aluminum small-block 5.3 L V8 with Active Fuel Management. The inline-six makes the TrailBlazer the most powerful six-cylinder SUV in its class. The Active Fuel Management system on the V8 engine shuts off 4 of the 8 cylinders during highway travel and idle to save fuel. The 6-cylinder versions of the TrailBlazer get up to 20 miles per US gallon (12 L/100 km; 24 mpg-imp) highway, according to refreshed United States Environmental Protection Agencyý estimates. EXT TrailBlazer line was the availability of a 3-row, 7-passenger EXT version. This vehicle was 16 in (406 mm) longer and had a higher roofline to allow easier access to the third row of seats. This roof was disguised by standard roof racks. Production of the EXT model was handled by the Oklahoma City Assembly plant in Oklahoma City, Oklahoma. The last TrailBlazer EXT rolled off the assembly line on February 20, 2006, because GM had reportedly closed that plant, making 2006 the final year for the TrailBlazer EXT. The EXT could be identified by its much straighter rear doors (which were not in-line with the rear wheel arches), as well as by the circular, metal cap on each of the quarter windows where the opening mechanism attaches. SS SS model was introduced for the 2006 model year. This was the first time a production SUV wore the Super Sport badge. This TrailBlazer came standard with a 6.0 L LS2 V8 based on the same engine that comes standard in the 2005-2006 Pontiac GTO. The LS2 is rated at 395 hp (295 kW) with 400 lb-ft (540 N-m) of torque and can accelerate from 0 to 60 mph in an estimated 5.8 seconds with quarter mile times around 13.5 seconds at 100 mph (160.9 km/h). Other differences entail the use of a heavy-duty 4-speed automatic transmission, a cold air intake package, a 4.10 ratio limited slip rear differential, a ZQ8 sport suspension, specially designed front brakes with brake pads similar to those found on the Corvette, and optional all-wheel drive (via a Torsen T-3 center differential). Safety Trailblazer's a Marginal overall rating in the frontal offset test while 2005-2009 models get an Acceptable rating. For 2008 models side curtain airbags became standard but the Trailblazer gets a Marginal overall side impact rating regardless of airbag configuration. Discontinuation The next generation TrailBlazer was to be built on an upgraded version of the current GMT360 platform called the GMT361. It was scheduled to be launched in spring 2007, but in January 2006, GM decided to just refresh the current platform and call the vehicle a GMT360NG. The Trailblazer, along with the Chevrolet Uplander, will be replaced by the Chevrolet Traverse. GM had closed the Moraine plant on December 23, 2008, ending production of all GMT360 products.
