Review NAMURA TECHNOLOGIES Piston Kit 0.75mm Oversize To 64.69mm

Introducing the Namura NA-40000-3 Piston Kit, a high-performance solution for your engine rebuilding needs. This piston kit is specifically designed for engines with a stroke length of 64.69mm and a piston diameter of 0.75mm.

The NA-40000-3 pistons are made from forged aluminum alloy, ensuring superior strength and durability. The forged construction process allows for precise control of the piston shape, resulting in excellent piston-to-wall clearance and reduced friction.

The piston tops feature a dished shape with a second compression ring groove, allowing for the use of two compression rings for optimal sealing and power output. The skirt of the piston is designed with a full-floating pin, allowing for minimal friction and reduced wear.

The piston rings included in this kit are made from high-quality, heat-resistant materials. The compression rings are made from a nitrided steel alloy, while the oil control rings are made from a chrome steel alloy. The rings are precision-machined to ensure a perfect fit and optimal ring land clearance.

The NA-40000-3 piston kit also includes piston pins, piston pin bushings, and piston pin retaining clips. The piston pins are made from high-strength, heat-treated steel, and the bushings are made from a high-performance, low-friction material. The piston pin retaining clips ensure secure retention of the piston pins.

In summary, the Namura NA-40000-3 Piston Kit is a top-quality solution for engine rebuilding. Its forged aluminum pistons offer superior strength and durability, while the high-quality piston rings ensure optimal sealing and power output. The piston kit includes all necessary components, making it a complete solution for engine rebuilders.
