At Parts Factory Australia, we stand behind every product we sell. That’s why every part comes with our 3-Year No Bullsh*t Warranty. If the part fails within 3 years due to a manufacturing defect, we’ll replace it or refund it — no fine print, no runarounds, no waiting weeks for answers.

It covers all parts we sell and all genuine faults — not damage from dodgy installs, crash damage, or backyard modifications. Just send us your proof of purchase and show us what went wrong — we’ll sort it fast.

We move through stock quickly, so you’re not getting old junk from the back of a warehouse. Our parts are fresh, current, and built to last — and if they don’t, we’ll make it right. That’s the Parts Factory promise. Simple. Honest. Aussie.

We prioritise fast and reliable shipping so you can get back on the road without the wait. Orders placed during business hours are dispatched immediately for fast turnaround.

✔️ Free Express Post on orders under 1kg – arrives in 2 days (3 days for WA)
✔️ Standard Delivery for any part – 2 to 4 days Australia-wide
✔️ Need it sooner? Upgrade to Express for just $15 flat-rate anywhere in the country

No delays, no excuses — just quick delivery and quality parts at your door. 

  • Trusted Aussie Supplier – Born and based in Australia, we understand the urgency of keeping your vehicle on the road. No offshore call centres, no slow imports — just fast, local service.

  • Fast & Free Shipping – Most parts are dispatched same-day with free express shipping on smaller orders. Need it quicker? Flat-rate express available. We don’t keep you waiting.

  • 3-Year No Bullsh*t Warranty – We stand by what we sell. If it fails from a genuine fault, we replace it or refund it. No excuses, no long waits — just honest backup.

  • Fresh, Up-to-Date Stock – We turn stock over quickly, so you always get the latest, most up-to-date versions — not old, dusty parts that have been sitting on shelves for years.

  • OEM Fitment, Affordable Price – We partner with medium-to-high-tier manufacturers to deliver OEM-matching quality without the dealership price tag.

  • Real People, Real Knowledge – Our team comes from hands-on, wrecking-yard backgrounds — we know cars, not just part numbers. Call us, message us, or visit — we’re here to help.
