About Us

A-Class Mechanical

We are a small WA family owned mechanical repair business for highway trucks established in 2010. We have a background in road transport both locally, interstate and into the Northwest region of Western Australia.

Some of our clients include stock transporters, general freight transporters and specialised freight transporters just to mention a few. Specialising in Caterpillar and Cummins engines, clutch and gearbox (Roadranger), driveline and diff repairs.

We aim to provide a top level service with the right advice, often using test parts to assess faults to ensure the correct parts are purchased the first time. General truck repairs and servicing are also performed so preventative repairs can be undertaken, minimising breakdowns and costly roadside repairs and / or towing.
