RPM 12 Gallon Auxiliary Fuel Tank for Speed UTV El Jefe

Go Further. Ride Harder. Worry Less.

Fuel range won't slow you down anymore. The RPM 12 Gallon Auxiliary Fuel Tank for the Speed UTV El Jefe is built for off-roaders who don’t know the meaning of "easy throttle." Whether you're blasting through dunes, running Baja, or conquering multi-day desert trails, this tank gives you an extra 12 gallons of capacity—nearly doubling your range with a worry-free install.

This system is precision-engineered with 6mm thick RotoMolded seamless plastic, making it tough enough for extreme terrain. It’s mounted low and centered under the factory seats, keeping weight balanced and helping you maintain high-speed stability without the rollover risk that comes from poorly placed add-ons.
