Chevrolet Silverado 1500 towing capacity, 2026 guide and earlier

The GCWR is where the number comes from

Chevrolet's trailer rating is not a figure of its own. The guide gives each Silverado a gross combination weight rating, the most the loaded truck and the loaded trailer may weigh together, then subtracts the curb weight and 300 lb of people to obtain the figure in the table (2026 Trailering Guide, p. 7 and pp. 26-27). The 2026 Silverado lines use only 7 GCWR values, from 14,000 lb to 19,100 lb. Two trucks on the same GCWR differ only by their curb weight, which is why a regular cab with a long bed often out-tows a crew cab with the same engine.

Working backwards from the top line, 19,000 lb minus 13,300 lb minus 300 lb implies a curb weight of 5,400 lb. The tool below starts from those two figures. Replace the curb weight with your scale ticket and the people and cargo with what you really carry: the result is the heaviest trailer the GCWR still allows, which is often below the table.

Max Trailering Package and wheel size

22 of the 50 lines in the 2026 table carry the Max Trailering Package, and every rating above 9,900 lb needs it. Follow one truck through the table to see what it changes. The Duramax 3.0L I-6 4x2 Double Cab with the standard bed is rated 9,300 lb as built, on a GCWR of 15,000 lb. With the Max Trailering Package it moves to 12,100 lb (GCWR 17,800 lb), and with the Max Trailering Package and 20" Wheels to 13,300 lb (GCWR 19,000 lb). The wheels matter because Chevrolet ties the highest GCWR to the 20-inch version in this guide; the lines with 18-inch wheels sit one GCWR step lower.

Tires count too. The 2024 guide's footnotes on p. 27 warn that the available mud-terrain tires change some Crew Cab 4x4 ratings (2024 guide). The ZR2 lines, printed as a separate short-bed 4x4, are rated no higher than 8,800 lb in 2026. Read the wheel and tire codes on the window sticker before choosing a line.

Engines from the TurboMax to the Duramax

The Duramax 3.0L I-6 covers the widest span, 8,700 lb to 13,300 lb, and holds the top line. The 6.2L EcoTec3 V8 follows closely at up to 13,200 lb, while the 5.3L EcoTec3 V8 reaches 11,300 lb with the package. The TurboMax® has no Max Trailering lines in the 2026 table and stays between 8,900 lb and 9,500 lb. These spans are wide enough that the engine alone does not tell you the rating; the cab, bed, drive and package each move it by a few hundred pounds or more. The F-150 and Ram 1500 pages show how the other half-tons compare, and the GVWR and GCWR guide explains the two ceilings.

Brakes, tongue and what the guide leaves aside

Chevrolet asks for trailer brakes on any trailer above 2,000 lb behind a Silverado (Chevrolet guide, p. 6), and for a tongue load of 10 to 15% of the loaded trailer. At the maximum rating the guide caps the conventional tongue at 10% of the trailer, 1,330 lb on the top line. The guide calls its maximum ratings figures for comparison only, since options and cargo reduce them. It also prints fifth-wheel and gooseneck ratings for the Silverado 1500 on pp. 28 to 30, which this page does not reproduce; read them in the guide itself if you plan a bed-mounted hitch. See the trailer brakes guide for the controller side.
