About Us
Since 2004, 4Blok has been supplying quality Holden, HSV, HDT and GMH parts to enthusiasts, workshops and restorers across Australia and around the world. Based in Mount Gambier, South Australia, we specialise in genuine, used, NOS and aftermarket automotive parts, along with selected American Muscle Truck and 4x4 components.
Who We Are
4Blok is an Australian automotive parts specialist based in Mount Gambier, South Australia.
Since 2004, we've been helping enthusiasts, restorers and workshops across Australia and around the world source quality parts for Holden, HSV, HDT and GMH vehicles, as well as American Muscle Trucks, 4x4s and classic Australian vehicles.
We stock a comprehensive range of genuine, used, NOS (New Old Stock) and aftermarket parts, from everyday replacement items through to rare and hard-to-find components. Whether you're restoring a classic Holden, maintaining your pride and joy, upgrading your truck, or searching for a discontinued part, we're here to help.
Personal Service Matters
Over the last few years, we've deliberately downsized the business to focus on what matters most — providing a more personal and dedicated service to our customers.
By operating as a smaller, hands-on team, we're able to spend more time helping customers find the right parts, answer technical questions, and ensure every order receives the attention it deserves.
What Sets 4Blok Apart
We don't just sell parts — we understand the vehicles they're fitted to. With more than 20 years of industry experience, we can help identify the correct part and provide practical advice based on real-world experience.
We take pride in the quality of our service and the condition of the parts we supply. Every part that leaves our warehouse is carefully inspected, cleaned where required, and professionally packed for safe delivery.
From Mount Gambier to customers across Australia, New Zealand, the United States, the United Kingdom and beyond, 4Blok continues to be a trusted source for Holden parts, American Muscle Truck components and specialist automotive parts.
Worldwide Shipping
We ship Australia-wide and internationally, helping customers access quality Holden, HSV, HDT, GMH and American Muscle Truck parts wherever they are located.
Whether you're located in Australia, New Zealand, the United States, the United Kingdom or elsewhere around the world, our team can assist with shipping options and freight quotes.
Flexible Payment Options
We offer a range of secure payment methods, including Afterpay and Zip making it easier to get the parts you need when you need them.
Thank you for supporting an Australian family-owned business.
