Stiletto PRO55A Replacement Brush Cutter Engine 51.7cc 1.8kW

More power. Less downtime. Get your brush cutter running again.

The Stiletto PRO55A is a high-performance 2-stroke replacement engine built on the proven Mitsubishi TL52 platform. With 1.8kW of peak power at 7000rpm and a generous 1100ml fuel tank, it's a step up in performance for most 40–55cc brush cutters — and it comes with a clutch included.

Strong, smooth, and quiet for its class, the PRO55A features a fuel-saving low-emission design that cuts running costs without sacrificing grunt. Easy recoil start and CDI electronic ignition mean reliable starts every time.

Note: This is a replacement engine only — no drive shaft or transmission included. Always wear safety goggles and ear protection when operating power tools.
