Import Cummins Qsx15 Piston — Buy in Bulk from Supplier in China

The Cummins QSX15 piston is a direct replacement component designed for heavy-duty diesel engines used in mining trucks, marine applications, and locomotives. It is manufactured to match original equipment dimensions and tolerances, with a forged aluminum alloy body and a coated skirt to reduce friction and thermal expansion. The piston is compatible with QSX15 engines produced between 1998 and 2018, and is not interchangeable with other Cummins engine families such as the QSK60 or KTA38.

Standard features include a reinforced crown with optimized combustion bowl geometry for improved fuel-air mixing, and a two-piece design with a piston pin and retaining locks. The piston ring grooves are hardened to withstand high thermal loads, and the skirt is coated with a low-friction material, typically molybdenum disulfide. These are typical specifications for aftermarket pistons in the Cummins QSX15 class, where OEM replacement parts are no longer available from Cummins for older models.

Buyers include engine rebuilders, fleet maintenance departments, and industrial repair shops in North America, Southeast Asia, and Eastern Europe. The component is sold individually or in sets of six for full engine rebuilds. Packaging is typically in anti-corrosion sealed bags with part number labels. Trade terms are usually FOB Guangzhou, with payment via T/T or L/C. Minimum order quantities are negotiable but typically start at one unit for sample verification.
