With this higher air/fuel ratio, your engine is now burning more raw fuel than the stock, lower compression piston. We are able to safely increase cylinder compression by approximately 1.25 points. This higher compression level increases cylinder pressure and temperature, resulting in more efficient fuel combustion. The combustion bowls in our Power Booster pistons have been specifically designed using modern technology to take advantage of performance opportunities that were originally left on the table by John Deere. The design of these pistons has been completely reassessed, reengineered and then rigorously field tested to ensure maximum power, efficiency and durability. It is also more resistant to corrosion, has more complete expansion, and better high-temperature strength. The piston is inherently stronger, with increased thermal characteristics, lubricity, and scuff resistance. Although hypereutectic pistons are still a cast piston, the addition of this extra silicon material gives several benefits over conventional cast pistons. Hypereutectic aluminum will typically have between 16-18 percent silicon in the alloy. Hypereutectic means effectively pushing this level of silicon beyond the normal amount that can be simply blended into the metal. This level, which is called the eutectic point, is around 12 percent. However, there is a limit to how much silicon can be utilized so it is evenly distributed without large nodes of silicon forming.

What's so special about Hypereutectic Aluminum? All Cast piston alloys use silicon, which increases the wear resistance, durability, and thermal characteristics of the aluminum.

To begin, they are manufactured with hypereutectic aluminum alloy.
