Sinotruk HOWO 400HP Piston 1000076563 – For Weichai WP12 Diesel Engine

Running a heavy-duty fleet requires parts that can take a beating. The 1000076563 Piston is specifically engineered for the high-compression environment of Sinotruk HOWO 400HP trucks equipped with the Weichai WP12 engine.

Unlike standard pistons found in lower-horsepower models, this unit is reinforced to handle the immense torque and thermal stress generated by 400HP+ operations. Manufactured with a specialized aluminum alloy and a re-contoured combustion bowl, it optimizes fuel burn efficiency while resisting thermal fatigue. If you are noticing power loss or excessive blue smoke in your HOWO A7 or T7H, replacing worn internals with this OEM-spec piston is crucial to preventing catastrophic engine failure on the road.
