- Performance Combustion Bowl: This isn't your average piston crown. The specially designed combustion bowl is engineered to resist erosion from the extreme pressures and advanced timing common in high-performance diesel engines, ensuring long-term durability.
- Lower Compression Ratios: Gain more control over your engine's performance. The reduced compression ratio gives you greater flexibility when tuning for high-output setups, allowing you to achieve maximum power safely.
- High-Strength Materials: Machined from durable OE castings, these pistons retain the cast iron ring insert, offering superior wear and fatigue resistance compared to other performance pistons.
- Grafal Skirt Coating: This proprietary graphite-impregnated coating dramatically reduces friction, improves oil control, and prevents scuffing, extending the life of your pistons and cylinder walls.
- Radiused Valve Pockets: Where applicable, fully radiused valve pockets minimize drag and increase scuff resistance, ensuring smooth operation even under intense conditions.
- Complete Kits: Each kit includes a full set of eight pistons, Mahle rings, wrist pins, and clips, providing everything you need for a seamless installation.
