4x4 Modifications Perth

Q: Are your modifications legal and roadworthy?

Yes. We follow WA modification guidelines and ensure everything is compliant and safe for road use.

Q: Do you install customer-supplied parts?

We may be able to install your parts – but we prefer to supply and fit to guarantee the quality and compatibility of what’s going on your vehicle. Please contact us directly to determine if we can install your parts.

Q: Can I combine mods with regular servicing?

Definitely. Many customers book a service and include mods like exhaust systems, lockers, or suspension at the same time.

Building your dream rig? Whether you're heading off-road, hauling heavy loads, or just want to get more out of your 4WD, Oceans Automotive offers expert 4x4 modifications in Perth. From suspension lift kits to engine reconditioning, we help you customise your setup for performance, reliability, and adventure.

Built for the Way You Drive

No two 4WD owners use their vehicle the same way — and that’s exactly why our approach to modifications is custom from the ground up. Whether you’re chasing more clearance, better torque, improved towing capacity, or full touring readiness, we’ll build it to suit your goals, your driving style, and your budget.

Our Perth workshop is fully equipped for mechanical upgrades, performance tuning, and off-road prep. We take the time to get it right — no shortcuts, no unnecessary extras — just real results, built for WA conditions.

Our Specialties

We offer a wide range of modification services and performance upgrades for all types of 4WDs, tailored to how you drive. Whether you’re building a tourer, a workhorse or a weekend off-roader, we’ve got the gear and the experience to get your vehicle set up right.

Engine Reconditioning

Restore power, improve reliability, and extend the life of your 4WD with expert engine reconditioning by Oceans Automotive. Whether your engine is tired, blowing smoke, or lacking the torque it once had, we’ll strip it down, rebuild it properly, and get it back to work — better than ever.

Engine Reconditioning

Cylinder Heads

A damaged or worn cylinder head can rob your engine of power, efficiency, and reliability — or worse, lead to major failure. At Oceans Automotive, we offer professional cylinder head repairs and replacements for 4WDs that work hard, tow heavy, or tackle the rough stuff.

Engine Replacement

Blown engine? Terminal failure? Time for an upgrade? Oceans Automotive offers full engine replacement services in Perth for 4WDs that need a fresh start — whether due to catastrophic failure, age, or performance goals.

Heavy Duty Clutch Upgrades

Towing heavy loads? Hitting steep tracks? Carrying extra weight with camping gear or trade tools? A standard clutch just isn’t built for that. At Oceans Automotive, we install heavy duty clutch upgrades that can handle the demands of real 4WD use — giving you better grip, smoother engagement, and longer lifespan under pressure.

Suspension Lift Kits

Need more clearance, better ride control, or a setup that actually handles the weight of your build? Oceans Automotive specialises in suspension lift kits for 4WDs in Perth — designed to help you go further, carry more, and drive with confidence on and off the road.

Diff Lockers & E-Lockers

Struggling with traction off-road? One spinning wheel can stop your entire rig - but not with a locker fitted. At Oceans Automotive, we supply and install diff lockers and electronic locking differentials (E-Lockers) for Perth 4WDs that are built for more than just bitumen.

Long Range Fuel Tank Install

Hate fuel stops breaking up your trip? Want to go further off the grid without worrying about the next servo? A long range fuel tank is one of the smartest upgrades you can make to your touring 4WD. At Oceans Automotive, we supply and install quality long range tanks designed to handle WA’s toughest conditions — with more fuel, more freedom, and fewer fill-ups.

Dual Battery Install

Powering a fridge, lights, comms, and other gear while off-grid? A dual battery system is essential for any 4WD setup that goes beyond the campsite. At Oceans Automotive, we install fully customisable dual battery systems designed to keep your accessories running — without risking a flat start battery.
