2010-2022 Lexus GX460 Auxiliary Fuel Tank System 18 Gallon

Description

The Helivue Design Auxiliary Fuel Tank System is a purpose-built 18-gallon aluminum fuel solution designed specifically for the 2010-2022 Lexus GX460 - whether you're a daily commuter logging long highway miles or a hardcore overlander pushing deep into the backcountry. Built 100% in the USA from thick 1/8" 5052 aluminum with a hammer finish satin black powder coat, this system is engineered to withstand real-world abuse at altitude and on rough terrain without compromise.

What sets this system apart is its no-compromise integration: it tucks above the bumper line to remain nearly invisible, preserves your factory KDSS, air ride suspension, and Class 4 receiver hitch, and keeps all OEM evap systems fully intact. It fills simultaneously with your main tank through the factory filler neck, and the included programmable transfer switch, fuel pump, and stainless steel sender give you complete control over fuel management when you need it.

Key Features
