Seal rings for the sleeve (2 pcs)
Advantages of the piston kit:
Selective assembly guarantees an extended service life of the engine kit.
High precision manufacturing: Modern high-precision equipment ensures micron-level accuracy in the production of kit components. This provides optimal clearances in each friction pair, achieving perfect compatibility.
Surface and coating of the sleeve: The working surface of the sleeve is processed using the flat honing method, promoting better oil retention. The fully phosphated sleeve is 100% protected against corrosion, and the internal surface has an additional finishing effect.
Thermoresistant coating: The piston combustion chamber surface is coated with a special thermoresistant coating called “Protect+,” which has no analogs. This coating protects the combustion chamber edges from thermal cracks, high-temperature gas erosion, and carbon buildup, promoting more complete fuel combustion.
Laser marking: High-quality laser marking is applied to the piston, sleeve, and piston pin.
Friction-reducing coating: The piston skirt is coated with a special friction-reducing coating called “Slide Pro,” which accelerates the running-in process, protects against scuffing, and reduces engine noise.
Microrelief: The microrelief on the working surface serves to increase the oil capacity of the piston, significantly reducing friction force in the piston-sleeve pair.
High wear and tear resistance: Tempering the outer surface of the pin provides increased resistance to wear.
