Caterpillar continues to be the global market leader in both heavy-duty and combined mid-range and heavy-duty truck engines.

In Australia, Kenworth Trucks named Caterpillar as its Supplier of the Year in its most recent awards, and in the US, OEM truck dealers ranked Cat the top independent engine supplier in the most recent annual survey.

But besides commanding the highest of engine quality, what really sets WesTrac supplied Cat engines apart, is our parts and service network.  Together with our partner, Energy Power Systems Australia, we can offer you the most comprehensive product support system in the industry.

So, no matter where you are, no matter what day of the week or time of day, Cat parts and service are never far away.  The Australia-wide network of 2500 Cat Dealer branches, including most major brand truck dealers, is the most extensive in the industry.  At each location, you have instant access to everything from information on engine selection, repair and maintenance options, to a full range of genuine Cat parts (normally off-the-shelf) and remanufactured components.
