2018 GMC Sierra 1500 towing capacity
The 2018 GMC Sierra 1500 towing capacity is very impressive. At 12,500 pounds of capacity, you can tow nearly anything, but you have to remember that all configurations of a truck are rated independently. In other words, there is actually a very specific configuration that gets you this capability. The 2020 GMC Sierra offers even more configurations and towing capacity for drivers who want the latest technology and performance metrics available.

Sierra 1500 max towing configuration
To achieve the 12,500 pounds of capability, you will need a crew cab with a short box in a two-wheel-drive configuration. You will also need the 6.2-liter V8 under the hood with a 3.42 axle ratio and the Max Trailering Package.

What’s included in the Max Trailering Package?
The Max Trailering Package for the Sierra 1500 gives you the upgrades you need to max out your towing numbers. It provides a trailer brake controller, improved shock tuning, heavier-duty rear springs, and an enhanced cooling radiator.

It’s also responsible for that axle ratio as it gives you a 9.76-inch ring gear. This makes for a 3.73 axle ratio on 6-speed transmission models and a 3.42 axle ratio on 8-speed transmission models. The Max Trailering Package is available as optional equipment on the SLE and SLT trim levels.
