THE GMC SIERRA RANGE

The GMC Sierra shares many features with its cousin, the Chevrolet Silverado. Based on the same chassis, drive line and body shell – The GMC Sierra SLT and the top of the line GMC Sierra Denali, turn heads with distinctive body designs and a highly optioned interior, loaded with creature comforts.

With its distinctive GMC grille and GMC Denali features, this GMC Sierra line provide a superb blend of working ability with absolute luxury.  The new 2017 GMC Sierra and 2017 GMC Sierra Denali come fitted with the LP5 Duramax which produces a stump pulling 331kW and 1,233Nm. To scale that out, thats nearly double the torque that a 2016 Landcruiser 200 series diesel produces and over 30% more horsepower.  Contact us for more information on the GMC range of trucks.

CHASSIS

The new 2017 GMC Sierra sports a rigid, high strength steel chassis and suspension system to make the Heavy Duty Sierra one of the strongest trucks available.

The entire chassis, suspension and braking system have been designed with heavy duty workload in mind. The chassis is now fully boxed through its entire length providing superior rigidity, payload and improving handling. Providing more payload than Dodge Ram, the 2500 GMC Sierra can carry up to 1,250kg in car license configuration.

To support the heavy payload the suspension is redesigned to include longer, wider leaf springs, heavier torsion bars and oversized shock absorbers compared to previous models. Also available is the Z71 suspension package, this includes off-road tuned Rancho shock absorbers, underbelly skid plates and downhill assist.

ENGINE CONFIGURATION

The GMC Sierra continues its partnership with the 6.6ltr Duramax Diesel engine and the Allison 6 speed auto.

The newly updated LP5 Duramax engine has just received a number of upgrades, the 2017 Duramax now produces 331kW and 1,233Nm, with a turbo-charged 6.6ltr V8.

The 2017 upgrades include – heavier duty rods, crank and pistons, a new turbo-charger, an even smoother exhaust brake, new injectors, acoustic suppression fro quieter running and the obvious through bonnet air intake system.

BRAKING

To allow greater braking confidence on long grades, or in tow/haul mode, Sierra 2500 Denali HD utilizes various technologies to 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
  • 4-wheel disc brakes with DURALIFE rotors.

There is an available Integrated Trailer Brake Controller for easy adjustments and displays the level of brake force or “gain” in the Driver Information Centre.
Trailer Sway Control Technology keeps both you and your trailer heading in the right direction,  using sensors to detect the rocking of a swaying trailer, and then applying the brakes to help bring it into line again.

TRANSMISSION

The power is transmitted to the rear wheels through the incredible Allison 1000 series 6 speed automatic transmission which features a triptronic manual shift mode and a driver selectable automatic tow/haul mode that reprograms the transmission allowing greater control while under load.

When engaged the tow/haul model down-shifts while descending a hill or even while slowing at the traffic lights to reduce the required braking effort. Providing additional safety and vehicle control the tow haul mode automatically changes gears as you would if you were driving a vehicle with a manual transmission.
