The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow. See your Chevy dealer for additional details.
  2. Gross Combination Weight Rating.
  3. NOTE: Trailer kingpin weight should be 15 to 25 percent of total loaded trailer weight (up to 1,500 lbs.). • Addition of trailer kingpin weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR).

TRAILERING BASICS

NOTE: Towing a trailer involves all major vehicle systems of your Chevy Truck, including powertrain, steering, suspension, tire and brake systems. Easy and safe trailering requires a properly equipped vehicle, additional trailering equipment and an appropriate trailer. It also requires loading both the vehicle and trailer properly, using safe driving techniques, meeting regional legal requirements and following break-in and maintenance schedules. The owner is responsible for obtaining the proper equipment (hitch ball, hitch type of the proper size, type and capacity) required to safely tow both the trailer and the load that will be towed. For more information, consult your Owner's Manual or speak to a trailering expert at your Chevy dealership. These charts will assist in determining how to best equip your Chevy Truck for trailering. To help you understand the charts, consider these trailering factors:

TORQUE: Indicates the strength of the engine. Low-end torque reflects how much force is generated to get your vehicle moving.

HORSEPOWER: Indicates how much work the engine does at a certain engine speed. At mid to high engine rpm, it's what keeps you moving at highway speeds.

AXLE RATIO: Along with your vehicle's transmission gears, a higher rear axle ratio contributes to how much available torque and horsepower (mechanical leverage) can be applied to the drive wheels for launch and uphill performance. Higher rear axle ratios, however, sacrifice fuel economy when not trailering.

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).

FIFTH-WHEEL TRAILERING: Often used with the heaviest trailers, fifth-wheel (or gooseneck) hitches are mounted on a pickup's bed with the trailer's kingpin weight located over or slightly in front of the tow vehicle's rear axle.

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 certification label located on the driver door or door frame.

GCWR: The Gross Combination Weight Rating is the total allowable weight of the completely loaded vehicle and trailer. A properly equipped tow vehicle and trailer at the maximum GCWR should be able to accelerate and merge with traffic, climb typical interstate 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.

TRAILERING CAUTIONS

NOTE: Please read this Trailering Caution safety information before trailering with a Chevy truck.

NOTE: The safety steps described here are by no means the only precautions to be taken when trailering. See the Owner's Manual for your Chevy Silverado for additional guidelines and trailering tips.

Trailering Caution: If you don't use the correct equipment and drive properly, you can lose control of your vehicle when you pull a trailer. For example, if the trailer is too heavy, your vehicle's brakes may be less effective. You and your passengers could be seriously injured. Pull a trailer only after you have taken the following steps.

Trailer Brakes: If your trailer weighs more than 2,000 lbs. 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 fluid 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 qualified individual make the brake fluid tap at the master cylinder port that sends fluid 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 more than 5,000 lbs.,(1) 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.

Hitches: It's important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are just a few reasons why you'll need the right hitch. Here are some rules to follow:

FIFTH-WHEEL TRAILERING: Silverado Pickup models can be equipped with a fifth-wheel or gooseneck trailer hitch.

  • Follow the hitch 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 centerline.
  • 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 Truck dealer can help you calculate the maximum allowable payload and GVWR required for your fifth-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.
