Who we are
Parts Donga is an independent supplier of diesel engine parts, specialising in Cummins and a broad range of other diesel power systems. We exist to give Australian operators access to quality parts at prices that actually make sense — not the prices you get handed when there's no other option.
We're here for the owner driver, the mobile mechanic working out of a ute, the small fleet trying to keep costs under control, the engine rebuilder who needs the right component at the right spec, or maybe it might be old mate with a boat who just wants to get back on the water! The everyday operators who keep things moving.
We import genuine OEM parts directly and know the product well enough to identify quality aftermarket alternatives that meet or exceed OEM specifications — passing those savings on to you. We understand what we're selling and we know how the engines work. We're not a pick-and-pack warehouse guessing at part numbers.
Diesel Engine Parts
Cummins is our main focus due to their growing presence in Australia. We directly import genuine Cummins parts, bypassing local dealers and source both genuine OEM and quality aftermarket components to suit everything from routine servicing through to major overhauls. We also cover parts to suit Detroit, MTU, MBE, Paccar, CAT, John Deere and Komatsu power systems. If it runs on diesel, chances are we can help.
From common service parts through to major components, we cover what keeps diesel power systems running. Cummins across the B, C, L, ISX, QSX and QSK series among others — with access to OEMs who supply components for other major diesel power plants across the board.
Built for the Industry
Owner drivers, mobile mechanics, small fleets, engine rebuilders and leisure craft owners — people who know what they need and just want to get it sorted without unnecessary back and forth.
The online store carries the parts that move most regularly and is growing all the time. Can't find what you're after? Reach out through the contact form and it'll get looked into.
For parts outside of what's listed in the store, current catalogues, microfiche, EPC systems and a growing network of overseas contacts are on hand to track down what the local market doesn't always carry.
Not everything is sourceable — but you'll always get an honest answer either way.
Downtime isn't just frustrating — for most it's expensive. A truck off the road, a generator down on site, a boat out of the water at the wrong time of year. Every day counts.
A straight answer on what can be done and a genuine effort to get it moving — that's the expectation here, and that's what gets delivered.
Experience You Can Count On
The team behind Parts Donga have spent their working lives in heavy industry parts across a broad range of equipment and applications. That hands-on background is what we draw on when something is hard to identify or hard to source.
Between current parts catalogues, microfiche, workshop manuals, EPC systems and a network of overseas contacts built up over the years, most things are findable. Get in touch via our contact form and we'll give you a straight answer on what's possible.
Parts Donga is an independent supplier and is not affiliated with, sponsored by, or endorsed by any OEM manufacturer. All parts supplied are either genuine OEM or quality aftermarket replacements.
