The Toyota Land Cruiser 40 Series (1960–1984) is one of the most iconic 4WD platforms ever built. Known for its durability and off-road capability, the 40 Series remains extremely popular in Australia for restorations, touring builds, and heavy-duty off-road setups.
Due to its long production run, tyre and wheel specifications vary slightly depending on engine type and market, but core fitment data remains highly consistent.
