Piston pin 23 x 1 pc
Piston rings ST-23 x 1 set
Retaining rings 60 x 2 pcs
Seal ring of the sleeve SMD9 x 2 pcs
Advantages of the piston kit:
Selective assembly
Selective assembly guarantees an increased 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, achieving perfect compatibility.
Surface and coating of the sleeve
Processing the working surface of the sleeve using the plateau honing method 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 special heat-resistant 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.
Anti-friction coating
A special anti-friction 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 force in the piston-sleeve pair.
High resistance to wear and damage
Tempering the outer surface of the pin provides increased resistance to wear.
