2015 GMC Sierra 1500 Maintains 12,000-lb Max Trailering

27 June 2014

The 2015 GMC Sierra 1500 maintains a 12,000-pound maximum trailering rating under SAE J2807 Recommended Practices – calculations being adopted throughout the industry. For 2015, the GMC Sierra 1500 builds on the strong foundation introduced with the redesigned 2014 model to offer uncompromising strength, capability and confidence.


Sierra’s 12,000-pound maximum rating is for the Double Cab 2WD configuration equipped with the available 6.2L V-8 engine and available Max Trailering Package. Trailering ratings for other configurations remain the same or are slightly lower, per the new SAE J2807 calculations. Examples of popular configurations with revised ratings include:


(Pre SAE  J2807)

(SAE J2807)

Double cab 4×4 5.3L V-8 6’ 6”  box 3.42 axle

9,600 lbs.

9,200 lbs.

Crew cab 4×4 5.3L V-8 5’ 8” box 3.73 axle

11,200 lbs.

10,800 lbs.

While the calculations for trailering ratings may have changed, the Sierra 1500’s powertrain and chassis features that support serious towing have not:

  • The available 6.2L EcoTec3 V-8 is the most powerful engine offered in the light-duty segment, with 420 horsepower and 460 lb-ft of torque. Like other EcoTec3 engines, it combines proven performance with advanced fuel-saving technologies, seamlessly switching to four cylinders to improve efficiency in light-load driving
  • The available Max Trailering Package includes a 9.76-inch rear axle, heavy-duty rear springs, revised shock tuning for increased control, enhanced cooling, and an integrated trailer brake controller. Also included is the G80 locking rear differential, a trailer hitch, and bumper-mounted four- and seven-pin connectors
  • Sierra’s standard 4.3L EcoTec3 V-6 and available 5.3L EcoTec3 V-8 also will offer significant towing capability for 2015, with maximum available trailer weight ratings of 7,600 pounds for the V-6 and 11,200 pounds for the 5.3L.

Customers should follow the trailering guidelines in their owner’s manual, ask their GMC dealer for trailering advice, or contact GMC Customer Assistance for more information. Additionally, the GMC Trailering Guide can be found in the Manuals & Videos section under the Ownership tab of the GMC.com Web site.

The foundation for all 2015 Sierra 1500 models and their trailering capability is a fully boxed, high-strength steel frame. Extensive use of high-strength steels in the frame and body structure also contributes to a quieter interior and more solid feel, and helps Sierra earn a 5-Star Overall Vehicle Score for safety in the newest government crash tests. Government 5-Star Safety Ratings are part of the U.S. Department of Transportation’s New Car Assessment Program.

GMC backs Sierra customers with the ProGrade protection program. It includes two years/24,000 miles (whichever comes first) of scheduled maintenance, covering four services of an oil change, tire rotation and 27-point inspection. It complements the three-year/36,000-mile (whichever comes first) bumper-to-bumper limited vehicle warranty and five-year/100,000-mile (whichever comes first) powertrain limited warranty for peace of mind.
