General Motors has unveiled the refreshed 2022 Chevy Silverado 1500 and 2022 GMC Sierra 1500, both of which introduce a long list of changes and updates for the pickup nameplates. Interestingly, tow ratings for both models is lower when using a fifth-wheel (or gooseneck) hitch, as compared to a standard ball hitch, and now, GM Authority is explaining the reason why.
Before we launch into an explanation why, let’s start by going over what we’re talking about.
Back in January, GM Authority published an in-depth look at the 2022 Chevy Silverado 1500 tow ratings and 2022 GMC Sierra 1500 tow ratings, providing a breakdown of the different model configurations and their respective max trailer weights. Critically, the tow ratings for both models are highest when using a standard ball hitch, with tow ratings decreasing when using a fifth-wheel or gooseneck hitch. For example, the highest tow rating for the refreshed 2022 Chevy Silverado with a ball hitch is 13,300 pounds, while the highest tow rating for the refreshed 2022 Chevy Silverado with a fifth-wheel gooseneck hitch is 9,900 pounds.
This may come as a surprise to some, especially when considering that GM’s heavy-duty trucks, the Silverado HD and Sierra HD, both offer higher tow ratings with a fifth-wheel or gooseneck hitch as compared to a standard ball hitch. Check out GM Authority’s in-depth look at the 2022 Chevy Silverado HD tow ratings and 2022 GMC Sierra HD tow ratings for reference.
To understand the difference, GM Authority reached out to General Motors and its engineering team.
As explained by GM, a fifth-wheel or gooseneck hitch places more weight onto the vehicle as compared to a ball hitch (15 percent typically, versus 10 percent). As such, the Gross Vehicle Weight Rating (GVWR) and Axle Weight Ratings (GAWR) become the limiting factor for towing in the light-duty trucks. By contrast, the HD trucks have much higher GVWR and GAWR’s, which means other factors become the limiters with regard to weight when towing.
With that mind, Chevy Silverado and GMC Sierra customers who plan to tow a trailer with a fifth-wheel or gooseneck hitch are advised to compare the numbers when considering the purchase of either an LD or HD pickup.
As a reminder, the refreshed 2022 Chevy Silverado 1500 and 2022 GMC Sierra 1500 are offered with four engine options, including the turbocharged 2.7L I4 L3B gasoline engine (now rated at 430 pound-feet of torque), the naturally aspirated 5.3L V8 L84 gasoline engine, the naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax. Under the body panels is GM T1 platform. Production takes place at the GM Silao Plant in Mexico and the GM Fort Wayne Assembly facility in Indiana, while the Silverado will also be produced at the GM Oshawa Plant in Canada in the near future.
