The Toyota LandCruiser 79 Series is one of Australia’s toughest and most trusted workhorses. Known for its solid axles, simple mechanical layout, and strong diesel engines, the 79 Series has become the backbone of farms, mines, touring builds, and serious off-road setups across the country. It’s built to handle abuse, but like any vehicle, the right upgrades can make it even more capable.
From the factory, the 79 Series is durable but often basic in refinement. Owners commonly look to improve torque delivery, braking performance, and overall drivability, especially once larger tyres, bar work, trays, or towing setups are added. The goal isn’t to change what makes the 79 great, but to enhance its usability in modern conditions.
At PPD Performance, upgrades for the 79 Series are selected with practicality in mind. Whether the vehicle is a daily work ute or a fully built tourer, the focus is on reliability and real-world performance.
One of the most common modifications for the 79 Series is improving engine response and torque. ECU tuning can significantly enhance low- and mid-range pulling power, which is especially noticeable when towing heavy trailers or climbing steep terrain. A well-developed tune helps the vehicle feel more responsive without pushing the engine beyond safe limits.
Supporting upgrades play an equally important role. Heavy duty clutches are often necessary on tuned or heavily loaded manual models, ensuring the drivetrain can handle increased torque without slipping. Brake upgrades are another popular improvement, particularly on vehicles carrying extra weight from trays, toolboxes, long-range tanks, and touring accessories.
Preventative upgrades like oil separator kits can also support long-term engine health, especially for diesel models working hard in dusty or remote conditions. These additions focus on protecting the vehicle over time rather than just increasing performance.
The 79 Series is commonly used in demanding environments, from job sites to remote outback tracks. That makes durability and safety critical. Upgraded braking systems provide greater confidence when descending hills or stopping under load. Improved torque delivery reduces engine strain when towing or carrying heavy payloads.
Because many 79 Series vehicles are built for long-term ownership, upgrades should add value over time. The right combination of performance, drivetrain, and supporting modifications can make the vehicle feel stronger, more controlled, and more capable without sacrificing its legendary toughness.
At PPD Performance, the focus is on supplying quality components tailored to the Toyota LandCruiser 79 Series 1999-2020, helping owners build reliable, hard-working utes that are ready for Australia’s toughest conditions.
