Flaming River Alternators are available in two styles, Billet HD High Output Alternators and Denso Style Racing Alternators. The Billet HD Alternators offer excellent output at extremely low engine RPM, more horsepower to the wheels and less energy wasted in the form of heat. The Denso Style Racing Alternators provide superior performance for drag racing and dirt track sports.

The Billet HD Alternators come equipped with precision balanced low-mass rotors, allowing these alternators to operate safely at shaft speeds of 20,000+ RPM. They also provide excellent output at speeds as low as 400 RPM. This high-low RPM operation gives the vehicle a broad operating range and more flexibility in the choices of the crankshaft pulleys. These alternators offer twin rectifier plates with double the amount of diodes over an OEM alternator, resulting in 300% more surface area to dissipate heat.
