Elite Engineering & Customization

Every Stinger Drive Gearbox is built to withstand the rigors of the marsh, river and ice

• Ultimate-Grade Materials: Featuring 356 T6 heat-treated aluminum cases and heat-treated helical-cut gears.
• Zero-Lash Precision: Our meticulous assembly sets gears at zero lash for whisper-quiet running and maximum gear life.
• Tailored to Your Build: Available in 7 different ratios (1.54 to 2.88) to perfectly match your propeller diameter, pitch, and engine torque band.

Master the Physics of Power

A Stinger gearbox doesn't just transfer power—it optimizes it. By reducing the input speed from the motor while simultaneously multiplying torque, our units allow your engine to stay in its peak power band while the propeller does the heavy lifting.

The Soft Drive Advantage

Experience the smoothest power delivery in the industry. Our specialized, high-load dampers are precision-engineered to absorb destructive torque spikes and minimize vibration between the engine flywheel and the gearbox. This "Soft Drive" technology ensures:

• Smoother Power Transmission: Fluid acceleration without the jarring shock of metal-on-metal.
• Enhanced Durability: Protects your drivetrain under the toughest conditions.
• Optimal System Reliability: Acts as a mechanical cushion for your entire propulsion system.

Pro-Tip for Maximum Longevity

To maintain peak 2026 performance, ensure you use high-quality gear oil (such as SAE-250 or 75-140) and perform regular inspections.

Reliable. Durable. Unstoppable. Enhance your ride today with the quiet strength of a Stinger Drives Soft Drive Gearbox.
