Form and function are integrated with a series of exterior features that help define Sierra 2500HD Denali’s signature look and enhanced practicality. The styling is accented by numerous chrome details, while the EZ Lift tailgate makes Sierra Denali more convenient and the underbody skid plates make it more resilient.

Sierra 2500HD Denali stands apart with its bold styling. Its presence is distinguished by Denali's exclusive full-chrome grille, chrome door handles, in addition to deluxe bodyside mouldings with a chrome top insert. The styling is accentuated with body-colour front and rear bumpers and requisite 18" polished aluminum wheels.

While GMC's engineers were focused on strength, they also ensured that ride quality wasn't sacrificed. Both objectives were accomplished by the sturdy, hydroformed, fully boxed frame that uses high-strength steel to increase structural rigidity, resist bending, twisting and shaking. This helps isolate road noise and contributes to Sierra HD's smooth driving dynamics.

Sierra 2500HD Denali standard rear vision camera makes it easier to see potential obstacles behind the truck


The standard rear vision camera makes it easier to see potential obstacles behind the truck when you are in reverse. It not only makes it easier to park, but also to back up to a trailer. The image is displayed in your rear-view mirror or navigation screen (if equipped). Rear park assist is also standard – it emits an audible alert when it detects an obstacle at the rear of the truck when you're backing up.

The GMC Sierra 2500HD Denali EZ Lift tailgate provides easier access to the pickup box


The standard, spring-loaded EZ Lift tailgate reduces the effort required to operate the tailgate, creating easier access to the pickup box. The tailgate can also be easily removed – and it locks to reduce the possibility of theft.

While the Sierra 2500HD Denali is equipped to premium specifications, the nuts and bolts of GMC Professional Grade engineering remain. That's the prerequisite that brings you to Sierra HD pickups – their ability to master the wide range of hauling demands you and other owners place on your trucks.

2014 GMC Sierra 2500HD Denali towing and hauling


Talk is one thing – the facts back up Sierra 2500HD Denali's promise of remarkable capabilities. It's the truck that's built for the kind of loads your business requires: The maximum conventional towing capacity is up to 5,897 kg (13,000 lb.)1 The maximum 5th-wheel towing capacity is 6,214 kg (13,700 lb.) with the Vortec V8 gasoline engine and 6,668 kg (14,700 lb.) with the Duramax® V8 Turbo Diesel.1 Payload capacities range up to 1,315 kg (2,899 lb.)2 with the Vortec V8 gasoline engine and 1,154 kg (2,545 lb.) 2 with the Duramax V8 Turbo Diesel.


Sierra HD Denali’s feature technologies that help you keep a trailer under your firm control. The standard trailer sway control system detects trailer sway and responds by automatically activating individual truck and/or trailer brakes and reducing engine power, if necessary, to bring the trailer back under control and keep it on your intended path. The standard integrated trailer brake controller measures brake force and applies the trailer brakes, as needed. The level of brake force or “gain” is displayed on the Driver Information Centre, while the controller itself is activated by a switch mounted on the instrument panel.


A heavily loaded truck places an added burden on the braking systems. Sierra HD Denali answers that demand with advanced braking technologies. The standard six-speed automatic transmissions include a grade braking feature that downshifts automatically when you apply the brakes on a downhill grade. This not only helps slow the truck – it also reduces brake wear. The available Duramax 6.6L V8 Turbo Diesel also features a push-button activated exhaust brake that closes the engine’s turbocharger vanes, creating back pressure that serves as an engine-brake, creating negative torque to help slow the vehicle. The result is reduced transmission and conventional brake wear.


The more you rely on a trailer, the more you'll appreciate the standard Trailering Special Equipment Package. It includes a series of heavy-duty, trailer-ready features that increase the ease of trailering. The package includes: a trailering hitch platform and 2.5-inch receiver with 2-inch adapter, a 7-wire harness with independent fused trailering circuits mated to a 7-way sealed connector, a wiring harness for aftermarket trailer brake controller, a single wire for a centre high-mounted stop light, plus a heavy-duty automatic locking rear differential and external transmission oil cooler.

Power meets reliability under the hood of the Sierra 2500HD Denali. Both the standard 360 horsepower Vortec 6.0L V8 gasoline engine and the available Duramax 6.6L Turbo Diesel are proven powertrains with a record of ironclad reliability. You can call it durable performance – and it's an essential component of GMC's Professional Grade engineering.

It's the tireless performer – the available Duramax 6.6L V8 Turbo Diesel generates a formidable 397 horsepower and 765 lb.-ft. of torque. All that peak torque is available at 1600 rpm – just above idle – giving you the pulling power you need to get enormous loads moving. Beyond its output, the Duramax 6.6L Turbo Diesel and Allison® 1000 Series six-speed automatic transmission combination has established an enviable service record, with more than 1.3 million units acting as a testament to their surefire reliability.


The Allison 1000 is specifically engineered to handle the high-torque loads of the available Duramax 6.6L V8 Turbo Diesel. The transmission isn't adapted from a light-duty unit – it's based on Allison's heavy-duty commercial and military applications. Tap-up/tap-down shifting, a smart exhaust brake, auto grade braking and tow/haul mode features are all included with the Allison 1000.


The standard Vortec 6.0L V8 gasoline engine incorporates a series of features and technologies that either boost output or enhance durability. Variable Valve Timing adjusts the opening and closing of valves to optimize torque output and fuel efficiency. High-flow cylinder heads enable increased output without the high compression ratios that require premium fuel. Durability features include polymer-coated pistons and the cam-in-block architecture that uses fewer moving parts. The Vortec V8 is teamed with the heavy-duty Hydra-Matic six-speed automatic transmission that uses a wide range of gear ratios, from an exceptionally low first gear to a sixth gear that delivers a very tall overdrive.


For excellent ride comfort with no sacrifice to strength, Sierra HD Denalis have an independent front suspension designed specifically for the constant punishment of HD use. The torsion-bar suspension design also allows you to make seasonal ride-height adjustments in minutes to compensate for the added weight of a snow plow, while the available Snow Plow Package enables you to attach a snow plow with ease.


No other competitor in its class offers a standard fully automatic locking rear differential for on- or off-road use. It delivers added traction by sensing a difference in speed between the left and right rear wheels and then locks the wheels so they turn in unison.
