SIERRA 1500 & 1500HD PICKUPS
NOTES:
• Any Sierra pickup can tow a 907 kg (2000 lb.) trailer without special equipment.
• Weight-Carrying Hitch Limit: 2268 kg (5000 lb.) trailer with 272 kg (600 lb.) tongue weight.
• A Weight-Distributing Hitch and Sway Control is required over 2268 kg (5000 lb.) Trailer Weight.
• Sierra 1500 models are limited to 2268 kg (5000 lb.) trailer rating unless equipped with
Heavy-Duty (Z85), High Performance (Z60), Ride Control (ZX3) or Off-road Suspension
Package (Z71).
• Ball hitch trailers over 2268 kg (5000 lb.) require optional Trailering Special Equipment
(Z82), which includes a weight-distributing hitch platform, extra capacity transmission
cooling, if not already equipped, a high capacity air cleaner, an electric brake control wiring
harness and a heavy-duty 8-lead wiring harness with a 7-pin connector.
• Trailer tongue weight should be 10-15% of the total loaded trailer weight (up to 454 kg (1000 lb.)
on 1500 models – 543 kg (1200 lb.) on models with option NHT, VortecMAX Performance
Package – 680 kg (1500 lb.) on 1500HD models).
• Addition of trailer tongue or kingpin weight must not cause the vehicle weights to exceed the
Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR).
• Trailer 5th-wheel kingpin weight should be 15-25% of the total loaded trailer weight (up to
680 kg (1500 lb.) on 1500 models – 1134 kg (2500 lb.) on 1500HD models). Fifth-wheel
trailers have a greater percentage of their weight on the kingpin (tongue load) than a
conventional trailer. Because of this, greater attention must be given to the maximum
allowable payload and GVWR.
• 1500 Short Box models are neither designed or intended to tow 5th-wheel or
gooseneck trailers.
GROSS COMBINATION WEIGHT RATINGS (GCWR) – 1500 AND 1500HD SERIES
Caution must be used when selecting a Sierra 1500 model to tow fifth-wheel
trailers due to limited payload and rear axle capacity to handle typical kingpin
weights. Payload capacity is reduced by the added weight of additional optional
equipment plus passengers and cargo in the tow vehicle. Sierra 1500 models can
tow 5th-wheel trailers, within the limits shown on page 9, as long as the kingpin
weight does not cause the vehicle to exceed the GVWR or GAWRs.
