Meet the 78mm piston, the unsung hero of modern engines. Precision crafted, it translates horsepower into reliability, smoothness, and enduring performance.
Designed for engines with a 78mm bore, this piston balances mass, strength, and heat management to deliver real-world gains in acceleration, fuel efficiency, and longevity. From the forging die to the finished skirt, every stage is a study in precision. The alloy—high-strength aluminum, optimized with a carefully tuned silicon content—keeps weight low without sacrificing rigidity. Tight tolerances, measured in microns, ensure consistent compression and minimal oil consumption across thousands of cycles.
Crown geometry is tuned for efficient combustion, reducing knock tendency and controlling peak pressure, while the valve reliefs prevent contact and promote reliable ring seal under high loads. The skirt receives an advanced coating to minimize friction and scuffing during cold starts, and the ring lands are reinforced to resist wear at high RPM. A refined lubrication geometry and optimized pin fit further cut friction, translating into cooler operation and longer life.
Thermal management is built into the design: a uniform cross-section and heat-favorable materials help dissipate heat quickly, so the piston remains stable even in demanding, high-speed runs. The result is steady power delivery, smoother idle, and a broader torque band. Available in standard weight or performance-tuned variants, the 78mm piston is ready for street, track, and off-road applications.
Quality is the cornerstone. Every batch undergoes strict dimensional checks, material verification, and functional tests that mirror real-world cycling—hot, cold, and varied loads. Our manufacturing partners hold ISO and IATF certifications, ensuring traceability from alloy ingot to finished part. Custom options abound: pin diameter, pin-to-top clearance, ring-land height, coating choice, and even bespoke crown profiles to suit specific engines.
For engineers and builders who demand consistency, fit, and peace of mind, the 78mm piston is a dependable partner. It reduces downtime, simplifies assembly, and unlocks smoother, more efficient performance across the operating envelope. Invest in precision. Choose the 78mm piston and empower your engine to perform at its best.
