Chevrolet Silverado and GMC Sierra light-duty pickups will maintain a 12,000-pound maximum available trailer weight rating as they transition to new ratings for 2015 based on SAE J2807 Recommended Practices.
“We engineered the new Silverado and Sierra 1500s to be our most capable light-duty pickups ever,” said Jeff Luke, executive chief engineer. “For 2015, we will build on that strong foundation to implement SAE J2807 while maintaining robust towing capability across the lineup.”
