JDY Stage 2 Pistons for BMW S58 G8X M2/3/4 Platform
The JDY Stage 2 Pistons are high-performance upgrades designed specifically for the BMW S58 engine platform. These pistons are engineered to handle extreme power outputs while offering enhanced durability and efficiency for high-performance and racing applications. Available in stock bore size (84mm) with a 9.2:1 compression ratio, they deliver outstanding performance and reliability under the most demanding conditions.
Key Features:
-
Piston Design:
- Stock Bore Size: 84mm.
- Compression Ratio: 9.2:1.
- Material: Billet 2618 alloy for high strength and lightweight performance.
- Available Options: Stage 1 pistons (up to 1500 HP) and Stage 2 pistons (up to 1800 HP).
-
Wrist Pins:
- Material: H13 super hard alloy.
- Dimensions: 23mm diameter, 0.225-inch pin wall thickness.
- Coating: Stage 2 pistons come with DLC (Diamond-Like Carbon) coating for reduced friction, enhanced wear resistance, and better performance under high temperature.
-
Piston Rings:
- ?equipped with Total Seal piston rings, which are thicker than OEM rings for better sealing, improved oil control, and enhanced resistance to higher combustion pressures.
-
Groove Re-Design:
- The piston ring grooves have been re-engineered for better heat management and durability, minimizing the risk of ring flutter and improving overall performance. Optimized groove depth ensures reliable sealing while accounting for thermal expansion under high-stress conditions.
-
Valve Pocket Design:
- Custom valve pocket grooves are designed to accommodate Kelford stage 1, 2, and 3 camshafts, allowing for better volumetric efficiency and greater valve lift without interference.
Stage 2 Pistons:
- Hard Anodizing: Provides a durable oxide layer for increased hardness, wear resistance, and corrosion protection. It also improves heat resistance and lowers friction between the piston and the cylinder wall.
- DLC Coated Wrist Pins: DLC coating ensures extremely low friction and enhanced durability, even in high-temperature environments, while reducing wear on the connecting rods.
- Performance Rating: Supports builds 1800+ horsepower, ideal for high-performance and racing applications.
Technical Specifications:
- Finished Bore Size: 3.307 inches
- Compression Ratio: 9.2:1
- Wrist Pin Diameter: 0.905 inches
- Wrist Pin Length: 2.250 inches
These pistons are engineered for compatibility with Kelford stage 3 camshafts, which allow for more valve lift, requiring deeper valve pockets that JDY has specifically designed.
