Product description

Engine piston rings QSL/QSC – reliability and precision

Piston rings for Cummins QSL/QSC engines, part number 4089644, are key components responsible for sealing, lubrication and engine durability. Made of wear- and heat-resistant materials, they ensure stable piston operation in the cylinder even under heavy loads and intensive use.

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.
