Why choose GSL?

How do our products give your diesel 4x4 the edge? If you’re driving a Land Cruiser or a Hilux, you’re likely pushing your vehicle beyond the ordinary. Whether you’re towing a caravan, carrying a large canopy, or tackling tough terrain on long trips, you demand exceptional performance from your 4x4. That’s why we design our products with your needs in mind.

Our goal is to ensure that our exhaust systems, air intakes, and cooling solutions outperform the competition. We use only the highest quality materials, set the benchmark for off-road readiness, and rigorously test our products on our own vehicles. Our exhausts are handcrafted in our workshop, our airboxes feature a triple seal, and our intakes are made from stainless steel. With GSL Fab, you can trust that every component is built to withstand your adventures.

Product Delays?

Please note that, due to increased demand of our products and delays in raw material supply, there is currently a 8-10 week wait for fabricated goods.

We understand you're eager to start your next adventure, and we're working hard to minimise our product wait times. While industry standards often lead to months-long delays, we're striving to keep our wait times to just a few weeks. By ordering supplies in bulk and keeping our team ready, we're committed to delivering the product you need as quickly as possible.

Tow with more power.

Get more from your diesel 4x4 with the right performance upgrades. Whether you’re towing a heavy load or carrying a substantial payload, ensure you have the power you need when you need it. Maximise your engine’s performance by improving airflow, maintaining optimal temperatures, and upgrading essential components. Our diesel performance products are designed to help you reach your destination with confidence.

Go the distance with improved reliability.

Protect your engine with components built for Australia’s extreme conditions: dusty, rough, and hot environments that demand exceptional durability and quality. We rigorously test and refine each product, then handcraft and assemble them to provide you with the ultimate confidence as you take your 4x4 into challenging new terrain.

Drive the rig you'll love.

Why settle for average? The journey should be as enjoyable as the destination. With GSL products, you’ll drive a 4WD that not only performs exceptionally but also looks stunning. Our brushed stainless steel, premium finishes, and precise fit ensure your rig stands out and sounds impressive. Enjoy every drive with a smile on your face.

"I have not found a better company to deal with and GSL are the only company I trust for my tuning needs. The 4" stainless exhaust was the first upgrade and I loved it, no better exhaust on the market. The turbo upgrade and the remap I absolutely love it as well.
Bite the bullet if you are from interstate or if you are a local send your Landcruiser to GSL, they welcome everyone who comes into the shop. They have years of experience and will happily take you through every product they sell and they do not give you the cold shoulder when you ask 100’s of questions. P.S I LOVE this company"

"There are tuners & then there are TUNERS.
There are accessories & then there are ACCESSORIES.
You can do a build from MILD to WILD .
If you want the best, from proven and tested performance upgrades, to fitting stainless & billet accessories , just think of 3 letters GSL . The people, the service, the honesty you get form everyone at GSL is something that is hard to find these days, not there though. I learnt more about how my LandCruiser worked & run than I could of imagined, there is not another workshop that i trust more . 
One very happy 79 series owner"

The Team at GSL Fab are fantastic. They build & supply high end quality diesel performance parts. What I like is the family friendly service & advice that they continue with even after the sale. As an example, I’ve had phone conversations with the owner principals on some faults I had running through my LandCruiser and after getting zero from the local Toyota service centre I rang GSL as a last resort, they helped by sending me a quick video which fixed my problems. This was over 18 months after I had purchased from them & did not relate to any of my purchases, but they still helped out. I’ve gone back to them a number of times now to progressively build out my Landcruiser 79. This business knows all the tolerance levels for the top end of your Toyota diesel engine and does real R&D on their own vehicles. What’s also cool is that I feel like they value my custom. I’m not just a sale. Ive invested $$$$$$ here because it’s that bloody good.
