Trailering
| TRAILBLAZER |
| NOTE: Your vehicle may require
additional special equipment to tow the maximum trailer weights listed here. The
weight-carrying hitch limit for TrailBlazer is a 4,000-lb. trailer with 400-lb. tongue
weight. Weight-distributing hitch and sway control required over 4,000-lb. trailer
weight. |

- 1 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 maximum trailer weight your vehicle can tow. See your Chevy dealer for
additional details.
- 1 GCWR: The Gross Combination
Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and
trailer including any passengers, cargo, equipment and conversion. 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
most road surfaces and stop adequately within a reasonable distance. The GCWR for your
vehicle should not be exceeded. USING GROSS COMBINATION WEIGHT RATINGS (GCWRs) TO
DETERMINE ENGINE, TRANSMISSION AND REAR AXLE RATIOS: You can use your desired GCWR
calculation to determine the powertrain you will require to tow a specific trailer with
your TrailBlazer. The last column to the right in the chart above shows the maximum
allowable GCWR based on all available TrailBlazer engine, transmission and rear axle
combinations. The GCWR includes the total loaded weight of both TrailBlazer and the
trailer.
- NOTE: Trailer tongue weight should be 10 to 15
percent of total loaded trailer weight (up to 750 lbs.). Addition of trailer tongue
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 doorframe. Base cooling system includes all content
required to attain maximum trailer rating. No optional cooling equipment available.
