The Chevrolet Small-Block fundamentally changed the world of engine performance more than six decades ago, and this icon of American horsepower is still going strong today. Or maybe you’ve chosen the iconic Big Block Chevy as your engine of choice. Big cubic inches and incredible torque throughout the power-band has made the Big Block a “go-to” engine for performance and durability.

Our precision machined billet case gear reductions were designed to be the strongest reduction drive alive. We have been very fortunate to put our Ballistic Drives in some very capable rigs, from severed duty work boats to high horsepower race boats the Ballistic has handled the demand. Our gears are CNC machined from 8620 billet steel and then case hardened to 62Rc. Gear sets are then ground and finish polished to AGMA Class 12 standards for smooth, quiet operation. With ratios ranging from 1.3 all the way to 2.9, we’re sure to have a ratio that will put you in the “sweet spot” of your engine and propeller combination.

Each new gear drive comes with an Industry Standard two (2) year warranty and Ballistics' limited lifetime guarantee against manufacturer defects.
