  • Maximum conventional trailering capacity of 14,500 lbs2
  • Maximum fifth-wheel trailering capacity of 18,000 lbs2
  • Maximum payload of 3,534 lbs3


Sierra 2500HD puts trailer safety and control at your fingertips. 


  • New Digital Steering Assist provides improved steering wheel feel at both highway and parking lot speeds by controlling fluid flow in the power steering system

  • Integrated Trailer Brake Controller provides fingertip control and monitoring of your trailer brakes

To let you engage an extra measure of braking confidence on long grades, or in Tow/Haul mode, Sierra 2500HD trucks utilize advanced technologies to ensure that you stay at your desired speed:


  • The Duramax diesel exhaust brake uses engine compression to create “negative torque” to help slow the vehicle
  • Grade Braking automatically senses when you want to slow down, and when the conditions are met, engages a Grade Braking shift schedule to help you maintain your desired speed
  • Duralife™ brake rotors protect against corrosion and can double life compared to conventional rotors.


Sierra HD’s available Trailering Package gives you the capability to trailer just about anything. Standard on SLE and SLT models, this package includes:


  • Trailer hitch platform
  • 2.5″ receiver with 2″ adapter
  • 7- and 4-pin wiring connectors
  • A rear-vision camera view that makes it easier to reverse and negotiate tight spaces while trailering
  • Available power folding trailering mirrors with LED rear guidance lamps to aid visibility when reversing


We built the Sierra 2500HD to deliver everything you expect from a heavy-duty truck—and then we exceeded those expectations with the most powerful Sierra ever.

The advanced DURAMAX diesel in the Sierra 2500HD pickup truck delivers 397 hp and 765 lb-ft of torque, making it the most powerful Sierra ever. The DURAMAX Diesel engine has a strong reputation and a proven track record with nearly 1.4 million sold since 2000.4 Paired with the sophisticated Allison® 1000 Series Transmission with overdrive, this available powertrain also offers a maximum highway range of up to 680 miles on a single fill-up.5


This ferritic nitrocarburizing technology is a GM-exclusive patented process that hardens and strengthens brakes. Duralife® protects against corrosion and can double the life of the brakes compared to conventional rotors.


The enhanced Allison 1000 is designed to handle the higher torque capability of the 6.6L DURAMAX engine, while also helping improve fuel economy and provide seamless assistance with the exhaust brake system.


For fast starts in cold weather, quiet operation and maximum efficiency, the direct injection system helps Sierra HD with the available DURAMAX diesel engine start in as little as 3 seconds at -40ºC and operates at nearly 30,000 psi to turn heavy diesel fuel into a fine mist, delivering low emissions and great power.


Sierra 2500HD delivers a smooth ride with a fully independent coil-over-shock front suspension and 3”-wide multistage rear leaf springs, which engage progressively as the load in the bed or the hitch increases.


From strong, steady power to bold acceleration on the highway, the 6.0L V8 with Variable Valve Timing (VVT) is up to any task by:


  • Delivering power when needed and efficiency when less power is called for
  • Monitoring and opening and closing valves for near peak levels of torque across the entire range of engine speeds


No other competitor in its class offers an available fully automatic locking rear differential for on- or off-road use.

  • Delivers added traction in driving and wheel-slip situations
  • Senses a difference in speed between left and right rear wheels, and then locks to turn both wheels in unison


  • Stay confidently in command of your truck and whatever you may be hauling or trailering. Available Hill Descent Control allows for a controlled descent in rough terrain without use of the brake pedal
  • StabiliTrak intelligently manages braking and throttle to help keep the vehicle on its intended path
  • Automatic Locking Rear Differential delivers increased traction
  • Driver Shift Control lets you shift gears up and down with the tap of the shift selector
  • Digital Steering Assist enables ease of handling at low speeds and improved steering feel at high speeds


Nearly two-thirds of the Sierra cab structure is made from high-strength steels. It’s a fortress of strength that contributes to the Sierra’s quiet cabin. We also use high-strength steel in our fully-boxed frame rails and major frame cross-members, the 2016 Sierra 2500HD is clearly a respected leader in the heavy duty truck example.
