Advantages of the piston kit:
Selective assembly
With selective assembly, an extended service life of the engine kit is guaranteed.
High manufacturing precision
Thanks to modern high-precision equipment, kit components are manufactured with micron-level accuracy. This ensures optimal clearances in each friction pair, achieving perfect compatibility.
Cylinder surface and coating
The honing processing of the cylinder’s working surface contributes to better oil retention. The fully phosphated cylinder 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 unique thermoresistant coating “Protect+” that protects against thermal cracks, high-temperature gas erosion, and carbon deposits, promoting more complete fuel combustion.
Laser marking
High-quality laser marking is applied to the piston, cylinder, and piston pin.
Anti-friction coating
A special anti-friction coating “Slide Pro” is applied to the piston skirt, accelerating the running-in process, protecting against scoring, and reducing engine noise.
Micro-relief
The micro-relief on the working surface of the piston serves to increase the oil capacity of the piston, significantly reducing friction in the piston-cylinder pair.
High resistance to wear and damage
The tempering of the outer surface of the pin provides increased resistance to wear.
