Description
Why Choose Brown Davis 81 Litre Auxiliary Tank for Lexus GX550?
The Lexus GX550 Brown Davis Long Range Fuel Tank is engineered for serious touring and real Australian conditions. When paired with the factory 80 litre tank, the extended capacity allows you to travel further between fuel stops, tow with confidence and maintain flexibility on long trips.
With a combined range of up to 1300 km (based on 12.3L/100km), this upgrade suits drivers who travel across remote highways, outback regions or long stretches with limited fuel availability.
