The GMC Sierra HD pickup will add several features for 2016, including active steering assist and a new gooseneck trailering package, according to General Motors.

Several double cab and crew cab models will add Active Steering Assist power steering to improve hauling and trailering with electronic controls that enhance road holding and stability on the highway. The feature also offers greater responsiveness and an improved steering feel. It won't be available on base models or regular cab models.

GMC is also offering the Gooseneck/5th Wheel Trailering Prep Package for larger trailers. GMC will offer the package in early 2016 for Duramax-equipped models. A frame-mounted hitch platform and tray accommodates a gooseneck ball hitch or fifth-wheel hitch-mounting brackets. The package also includes a cargo bed-mounted trailer harness. A new Gooseneck Completion Kit will also be available from GMC dealers, featuring a 2-5/16-inch ball hitch and two chain tie-downs.

For 2016, GMC has aligned the Sierra HD with SAE J2807 towing standards. Maximum trailer weight ratings for the truck include 14,500 pounds for the 2500HD, 18,000 pounds for fifth-wheel/gooseneck trailering, 15,000 pounds for the 3500HD single rear wheel conventional trailering, 17,500 pounds for single rear wheel gooseneck trailering, 20,000 pounds for 3500HD dual rear wheel conventional trailering, and 23,200 pounds for dual rear wheel gooseneck trailering.
