Sinotruk HOWO 371 Piston VG1560037011 – Reinforced Alloy for WD615.47 Engine

The piston is the heart of your truck’s combustion system, and for the classic HOWO 371 dump trucks, there is no room for compromise. The VG1560037011 Piston is manufactured to strict OEM standards to withstand the intense pressure and heat generated by the Weichai WD615.47 diesel engine.

Cheap aftermarket pistons often suffer from poor thermal conductivity, leading to expansion issues and potential cylinder liner damage (“scoring”). This unit is cast from a high-silicon aluminum alloy, designed to maintain its shape even under heavy load climbing or long-distance hauling. It features a precision-machined combustion bowl and graphite-coated skirt to reduce friction and noise inside the cylinder block. Whether you are doing a single-cylinder repair or a complete engine rebuild, this piston ensures your HOWO gets its original compression and power back.
