Features
?Piston Kit
- High-temperature resistance A2618 material is used for thinner wall thickness and lighter weight.
- Machining process reduces waste parts and achieves the lightest weight possible.
- Bridge shaped structure increases rigidity of the unit and allows weight reduction.
- The shape of the crown surface is kept as close as possible to that of the stock.
- Nickel plating above the top ring slot improves knock and wear resistance.
- Leads the cooling oil from the 3 oil jets to the proper location for effective cooling.
- 2-layer coating improves anti-seizing and reduces friction.
- Shortening the piston pin reduces the weight of the piston pin boss section.
- Dedicated pins with appropriate wall thickness are set to reduce weight.
?Connrod Kit
- Features machined nickel-chrome alloy I-beam connecting rods.
- 25% stronger than the stock product.
- Compatible with D24mm piston pin.
- Surface is finished with a WPC treatment to improve durability.
