Chevrolet offers a comprehensive lineup of vehicles, powertrains and axle ratios to tackle your trailering needs. From the capable Colorado to the all new 2007 Silverado HD, there is a vehicle to  t your purposes  whether you’re taking your ATV to the closest two-track or trailering a front-end loader to the job site. Chevy offers 10 vehicles that can tow more than 3,500 lbs., with four eclipsing 10,000 lbs.* Factor in the Kodiak C4500, and Chevy offers towing capability to meet almost any need. The information on the following pages will help guide you in the selection of your next vehicle. Chevy Trucks the most dependable, longest-lasting trucks on the road. NOTE: Some of the vehicles shown in this catalog have been altered or up tted with equipment supplied to Chevrolet by independent suppliers. See notes on alterations and warranties on page 14. *When properly equipped. Maximum trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the rating, plus driver. The weight of other optional equipment, passengers and cargo will reduce the maxi- mum trailer weight your vehicle can tow. See your Chevy dealer for additional details. Dependability based on longevity: 1981 July 2006 full-line light-duty truck com- pany registrations. Excludes other GM divisions. FEATURES FEATURES LE AD. DON’T FOLLOW. Chevy separates itself from the competition by offering segment-exclusive features that help you get the most out of your trailering experience. There are 11 Vortec gasoline engines for you to choose from, ranging from the dependable 2.9L I-4 to the impressive Vortec MAX 6.0L V8 that pumps out 367 horsepower.  The available Duramax Diesel 6.6L V8, when coupled with the GM-exclusive* Allison 1000 Series six-speed automatic trans- mission, generates best-in-class diesel horsepower and 660 lb.-ft. of torque more than any competitor.*  The available Allison automatic transmission offers a GM heavy-duty truck-exclusive* Tap-Up/Tap-Down shift feature available on Silverado HD and the medium-duty Kodiak  giving you added control of the trans mis sion when you’re towing.  Many Chevy models offer different axle ratios to help customize a new Chevy to meet your needs. A Tire Pressure Monitor System is available on select vehicles. Every 2007 Chevy light-duty truck and pas- senger car is backed by a 100,000 mile/ 5-year Powertrain Limited Warranty. * Based on GM Large Pickup segment and 2007 competi- tive information. Whichever comes rst. See dealer for details. **Available on select models. Requires available Navigation Radio and head-curtain side air bags. TOW/HAUL MODE enhances perfor- mance while pulling a trailer or hauling heavy loads. When activated, this feature reprograms the automatic transmission shift schedule and helps reduce undesired transmission shifts. INTEGRATED TRAILER BRAKE CONTROLLER is available on all Silverado HD trucks. The controller provides immediate and measured brake force signaling to electric-controlled trailer brake systems. Since it’s fully integrated with the vehicle’s ABS and electric systems, you don’t have to have an external and/or aftermarket brake control system. REARVIEW CAMERA SYSTEM** allows the driver to use the available naviga-tion screen to see obstacles that are located behind the vehicle. The camera is offered with the available Ultrasonic Rear Parking Assist, notifying the driver of stationary obstacles up to 2.5 meters behind the vehicle while traveling in reverse at low speed. The GM-exclusive* automatic locking rear differential enhances performance in a variety of conditions, including on boat ramps. 5 8 TR AILERING DEFINED. The language found in the trailering world can seem as tricky to the rst-time hauler as any brainteaser, so we’re providing a quick tutorial on towing-speci c terms. On page 7, you’ll  nd important vehicle braking requirements and vehicle weight ratings, along with terms like Gooseneck Trailering and Gross Combination Weight Rating (GCWR).  Also, you’ll nd an industry breakdown of the ve different trailer classes to aid in your vehicle selection. 6 TrailBlazer LS 2WD shown in Imperial Blue Metallic with available features. W EIGH T- CA RRYING LIGHT-DU T Y HITCH WEIGHT-DISTRIBUTING HITCH PL ATFORM GOOSENECK HITCH WEIGHT-DISTRIBUTING HITCH WITH SWAY CONTROL FIF TH-WHEEL HITCH Before examining the trailering charts, take a moment to review the following information. This review will help in your understanding of the charts and help provide a safe trailering experience. TRAILER BRAKES: If your trailer?s weight ranges from 1,000 to 2,000 lbs. when loaded, then it must have its own adequate brakes. Be sure to read and follow the instructions for the trailer brake controller so that it is installed, adjusted and maintained properly. ? Don?t tap into your vehicle?s brake system if the trailer?s brake system will use more than 0.02 cu. in. of ? uid from your vehicle?s master cylinder. If it does, neither braking system will work well. You could even lose your vehicle brakes. ? The trailer brake parts must be able to take 3,000 psi of pressure. If not, the trailer brake system must not be used with your vehicle. If everything checks out thus far, have a quali? ed individual make the brake ? uid tap at the master cylinder port that sends ? uid to the rear brakes. Don?t use copper tubing because it will bend and ultimately break. Use only double-walled steel brake tubing. ? If you?ll be towing a trailer that, when loaded, will weigh between 4,000 to 7,500 lbs.*, be sure to use a frame-mounted, weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when you?re driving. AXLE RATIO: An axle ratio is the ratio between the driveshaft revolutions per minute and the rear axle?s revolutions per minute. A higher axle ratio is better for quick acceleration, climbing grades, carrying loads or pulling a trailer. BALL HITCH TRAILERING: There are two types of ball hitches. A weight-carrying hitch consists of a ball and coupler with no means to distribute the hitch weight. It is used primarily for lightweight trailers. Heavier trailers, however, require a weight-distributing hitch, which uses spring bars to transfer some of the hitch weight forward onto the tow vehicle?s front axle and rearward onto the trailer?s axle(s). RGAWR AND GVWR: Addition of trailer hitch weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the certi? cation label located on the driver door or door frame. GCWR: The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer. A properly equipped tow vehicle and trailer at the maxi-mum GCWR should be able to accelerate and merge with traf? c, climb typical grades at highway speeds, handle the combination on virtually all road surfaces and stop adequately within a reasonable distance. MAXIMUM TRAILER RATING: This rating is determined by subtracting the tow vehicle?s weight (curb weight) from the GCWR. When a base vehicle (curb) weight is used, additional passenger, equipment and cargo weight reduces this rating. FIFTH-WHEEL TRAILERING: Silverado Pickup, Chassis Cab and Kodiak models can be equipped with a ? fth-wheel or gooseneck trailer hitch. ? Follow the manufacturer?s directions for installation, but note that the hitch must be attached to the truck frame. Do not use the pickup bed for additional support. For proper kingpin tongue load distribution and control of the trailer, the hitch must be mounted so the kingpin load is placed ahead of the rear axle center line. ? Fifth-wheel trailer kingpin loads are higher than conventional trailer tongue loads, so pay careful attention to the truck?s payload capacity and rear axle weight ratings. ? Your Chevy dealer can help you calculate the maximum allowable payload and GVWR required for your ? fth-wheel trailering application. The weight of any additional equipment and all passengers other than the driver must be subtracted from the payload weight to determine the maximum kingpin load available. TORQUE: Indicates the strength of the engine. Low-end torque re? ects how much force is generated to get your vehicle moving. *See your dealer for details. 7,500 lbs. on Silverado 2500HD and 3500HD models. Maximum trailer rating may be less, depending on powertrain combinations.

Vortec Engines GM Powertrain engineers were able to design a vortex inside the combustion chamber of an engine, helping create a better air-to-fuel mixture in the combustion process. This helps Vortec engines deliver great horsepower, impressive durability and low maintenance requirements. 2. Active Fuel Management? With Active Fuel Management,? power is delivered when needed. In situations where eight-cylinder power isn?t needed, Active Fuel Management? deactivates four cylinders with seamless precision. When load demands increase, all cylin-ders are reactivated to provide eight-cylinder performance. Active Fuel Management? can be found on the Vortec 5.3L V8 and Vortec MAX 6.0L V8 engines. 3. Transmission Cooler Many Chevrolet vehicles can be equipped with an auxiliary external transmission cooler that is designed to help reduce heat stress when towing heavier loads. 4. Automatic Locking Rear Differential On select models, the available GM segment-exclusive* automatic locking rear differential allows additional traction at lower speeds on snow, mud and ice. If one of the rear wheels has traction while the other does not, the locking rear axle automatically sends power to the wheel with grip to move the vehicle. When needed, the automatic locking rear differential can provide full lockup for maximum drive power to both rear wheels. 5. Tow/Haul Mode When activated, Tow/Haul mode enhances trailering by altering the transmission shift schedule when transporting heavy loads and improves overall transmission cooling. Standard on select models. 6. Autotrac Transfer Case New, lighter transfer case assemblies with aluminum housings,optimized low-range gears and electronic shift controls with new, more reliable contactless sensors help the available Autotrac active transfer case in Silverado 1500 4×4 models to better adjust to varying road conditions. The Autotrac system features four drive modes (2HI, AUTO/4WD, 4HI and 4LO) plus a neutral setting. CHEV Y TRUCKS DON?T HAVE PARTS. THEY HAVE GUTS. 5 2 3 1 6 11 7.

Dynamic Rear Proportioning Dynamic Rear Proportioning (DRP) is a braking system that optimizes braking performance under varying cargo load conditions. DRP also recognizes rear-brake lockup and regulates the pressure applied to the brakes. Standard on select models. 11. Multiple Suspension Choices Whatever the task, there?s a Chevy vehicle with the right suspension to get the job done. Visit chevy.com to see what suspensions are offered for the vehicle of your choice. Allison Six-Speed Automatic Transmission Available on Silverado HD models, the Allison six-speed automatic transmission has a number of technological advancements that further enhance driver control when hauling or pulling big loads. These include: ? Tow/Haul mode that limits shift cycling and improves overall transmission cooling. ? Driver shift control with Tap-Up/Tap-Down shifting that allows manual control to select upshifts and downshifts. ? Automatic Grade Braking uses the engine and transmission to slow the vehicle on downhill grades. Duramax Diesel The Duramax Diesel engine is compatible with B5 biodiesel fuel blends, which use 95 percent petroleum and 5 percent biodiesel ? a renewable, organic fuel. Available on Silverado HD and Express 2500 and 3500 cargo models. *Based on GM Large Pickup segment and 2007 competitive information.
