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:

  1. 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).
  2. 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.
  3. 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.
  4. 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.
  5. 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.

Why Choose JDY Pistons?

JDY’s Stage 2 piston kits are meticulously crafted for enthusiasts and professionals aiming to push the limits of their BMW S58 3.0T engines.  JDY’s pistons provide the durability, power, and performance needed for success on the street or track.
