Product Design Philosophy
Reinforced aluminum alloy with Alfin oil gallery and crown anodizing withstands turbocharged pressures. Precision-machined for 4HG1T engines, ensuring durability under high thermal and mechanical stress in NPR trucks.
How it works
Reciprocates in the cylinder to compress air for combustion. Alfin oil gallery cools the ring groove area; reinforced skirt transfers combustion force to the crankshaft, driving the NPR truck.
Problems the product can solve
Solves piston cracking, ring groove wear, and power loss caused by turbocharged 4HG1T engines. Restores compression efficiency and thermal stability for heavy-duty NPR operations.
