Chevrolet Silverado 2500HD LTZ

To get through the most demanding jobs.

You don’t get to be the most dependable, longest-lasting full-size pickups on the road by tampering with what works. You build on proven success. You make your best even better.

The all-new 2020 Silverado HD is the strongest, most capable Silverado HD ever, with class-leading technologies and an expanded range of customer choices.

The all-new 2020 Silverado HD is longer, wider and taller than its predecessor, with a wheelbase that’s been stretched 13.2 centimetres on Crew Cab models and is scaled for HD customers. It is available in five trim levels: Work Truck, Custom, LT, LTZ and High Country, offered across 22 cab, bed, chassis and driveline configurations.

There’s the legendary Duramax 6.6L V-8 Turbo-Diesel, making 332 kw and 1233 nm of torque, coupled with an all-new Allison® 10-speed automatic transmission.

In addition, every component on the Silverado HD, between the transmission and the wheels, has been upgraded to enable an increase in max towing capability — up up to 15.8 tonne (requires 3500HD regular cab 2WD with dual real wheels, available diesel engine and gooseneck hitch).

2020 Silverado HD highlights:

  • All-new Allison® 10-speed automatic transmission is matched with the available Duramax 6.6L V-8 Turbo-Diesel engine for a 52 percent increase in max towing to 15.8 tonne on properly equipped models.
  • Autotrac active two-speed transfer case on 4x4 models electronically controls “4 Auto” mode, allowing the truck to seamlessly shift between two-wheel drive and four-wheel drive based on road conditions.
  • Advanced Trailering System technologies and new transparent trailer view: The in-vehicle trailering system features an available total of 15 available camera views (requires an installed accessory camera), such as HD Surround Vision and other unique views including a transparent trailer feature to help provide added confidence when towing. 
  • HD-exclusive sculpted exterior design features the most differentiation from the Silverado 1500 ever — the roof is the only shared sheet metal.
  • BedSteps feature and larger CornerSteps makes it easier to load or reach items in the cargo bed, which is designed to hold a pair of size-12 boots and up to 220 kg.
  • Larger cab enables more spacious interiors with Crew Cab models adding about 7.6 centimetres in overall length.





New Allison® 10-speed transmission matched with proven Duramax 6.6L Turbo-Diesel

Maximum power and towing capability in new Silverado HD lineup comes from the proven Duramax 6.6L V-8 Turbo-Diesel with 1233 Nm of torque. Its towing capability is increased up to 52 percent with driveline improvements including the addition of the all-new Allison® 10-speed automatic transmission — a legendary Duramax/Allison® combination that contributes to the Silverado HD’s 15.8 tonne max towing rating*, when properly equipped.

A diesel after-run feature specifically for use following a demanding towing situation is an additional new technology for the Duramax engine. The after-run allows the engine to keep running for up to 15 minutes to allow it to cool down using the fan and circulating coolant. If the driver puts the truck in park when an after-run situation is needed, an alert will appear on the driver information cluster directing them to keep the engine running for cool down. Should the customer ignore the message and exit the vehicle, the truck will restart on its own via remote start mode for cool-down. At that point the customer can walk away and the truck will turn itself off when the engine reaches an acceptable temperature.

The all-new Allison® 10-speed automatic transmission combined with improved driveline components is better at transferring all of the Duramax’s torque to the pavement, allowing more torque to be put to the ground in lower gears, enhancing the overall driving dynamics and trailering with smoother gear changes and shorter steps between them. It also supports smart engine braking, which can help reduce brake wear. The Duramax/Allison® combination’s standard axle ratio is lowered to 3.42:1, which reduces engine speed, therefore enhancing refinement.

For customers powering other equipment with their trucks on the job site, an all-new, factory-integrated engine-driven Power Take Off (PTO) is available and eliminates the need for an aftermarket unit. Exclusively offered with the Allison® 10-speed transmission on select diesel models, it’s the first fully integrated PTO system of its kind in the HD truck segment, with the PTO’s drive gear operated via chain to direct engine power. And because it is engine-driven rather than turbine-driven, owners can use the PTO while the vehicle is idling. A button inside the cab enables the PTO, and a mode selector allows adjustment of load and torque output.



To accelerate when trailering or hauling heavy loads, Tow/Haul mode raises transmission upshift points. It also raises downshift points using engine compression to help slow your Silverado HD instead of merely braking.



Silverado HD’s new available 10.5 cm diagonal colour Driver Information Centre (DIC) lets you choose from a menu of display themes to select what information you see and how you see it.



The available Z71 Off-Road Package features suspension upgrades designed for rugged off-road terrain, including Rancho® twin-tube shocks, an Underbody Skid Plate Package, all-terrain Tyres and Hill Descent Control. Inside and out, the Z71 has rugged looks, with a unique Z71 gauge cluster, including a unique Off-Road screen in the Driver Information Centre, and grille. Custom Z71 graphics on the instrument cluster and pickup box, as well as brushed-aluminium sill plates and special interior accents, make this truck not only tough but stylish.

Performax International offers an industry exclusive three year/100,000km factory backed new car warranty with 24 hour Road Side Assist. This is backed 100% by our factory; it is not an after-market new car warranty or mechanical warranty as favoured by most companies.

A Performax Warranty is all about looking after the customer, not looking for reasons to decline a claim. The customer doesn’t call an office in a major city and talk to an operator that knows nothing about the vehicle, and only thinks of them as a number; they call their Performax Dealer or Head Office and deal direct with an employee that usually knows what they are talking about.


Performax International operates the only original equipment manufacturer (OEM) style dealership network in Australia, with dealers throughout the country stocking and servicing our vehicles. Customers often question the ability to get help when travelling in remote areas; it’s no different to any other modern vehicle.

Basic repairs can be done anywhere by any competent mechanic, and Performax is happy to offer them assistance over the phone. Most common parts are carried in Australia and can be despatched same day, just like a Toyota. And just like a Toyota if it’s not a common replacement part it gets flown in from overseas usually within seven to 10 days.


Performax International carries an extensive range or spare parts, genuine and aftermarket accessories. Customers have the ability to customise their vehicles to suit the application, whether it be outback touring, heavy duty towing, or a show pony we can accommodate.


Brought your own vehicle in to Australia for us to convert it? Your conversion has its own 12 month / 20,000km warranty.
