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 Chevrolet dealer for additional details.
2 Gross Combination Weight Rating.
GENERAL TRAILERING NOTES
A 7-wire trailering harness is standard on Silverado HD models. Where available, the Heavy-Duty Trailering Equipment Package (Z82) provides a trailer hitch
platform and a 7-pin sealed connector at the rear bumper. An 8-wire camper/fifth-wheel wiring harness (UY2) is also available and requires the Heavy-Duty Trailering Equipment Package (Z82).
AUTOMATIC TRANSMISSION MODEL NOTE
All automatic transmission models are equipped with an engine oil cooler (KC4) and an oil-to-air transmission oil cooler (KNP).
FIFTH-WHEEL/GOOSENECK KINGPIN WEIGHT NOTES
Fifth-wheel or gooseneck kingpin weight should be 15% to 25% of total loaded trailer weight. The addition of trailer kingpin weight cannot cause vehicle 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. Fifth-wheel hitch is available as a dealer-installed
accessory on select models. See the Trailering Basics for more trailering information.
FIFTH-WHEEL/GOOSENECK TRAILERING NOTES
Silverado HD can be equipped with a fifth-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 (over or slightly) 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 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
must be subtracted from the payload weight to determine the maximum kingpin load available.
