Advantages of the piston kit:

Selective assembly
Selective assembly guarantees an extended service life of the engine kit.

High precision manufacturing
Thanks to modern high-precision equipment, kit components are manufactured with micron precision, ensuring optimal clearances in each friction pair and achieving perfect compatibility.

Sleeve surface and coating
The honing treatment of the sleeve’s working surface contributes to better oil retention. The fully phosphated sleeve is 100% protected against corrosion, and the internal surface has an additional finishing effect.

Heat-resistant coating
The piston combustion chamber surface is coated with a unique heat-resistant coating called “Protect+,” which protects the edges of the combustion chamber 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
A special friction-reducing coating called “Slide Pro” is applied to the piston skirt, accelerating the running-in process, protecting against scuffing, and reducing engine noise.

Microrelief
The microrelief on the working surface of the piston serves to increase the oil capacity of the piston, significantly reducing friction in the piston-sleeve pair.

High resistance to wear and damage
The tempering of the external surface of the pin ensures increased resistance to wear.
