Description

Piston rings provide combustion chamber sealing, oil consumption control and even force distribution in the piston-rod assembly. The use of advanced alloys and precise manufacturing increases engine life, reduces blow-by and compression losses. Designed for diesel engines used in construction, industrial and heavy-duty vehicles.

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
