Once you’ve felt the power of a 440 big bore kit, you’ll appreciate the work that goes into Wiseco’s Big Bore Replacement Piston.
Wiseco makes their big bore pistons to exacting standards needed to withstand the incredible forces and power big bored engines put out. That’s why Wiseco uses forged pistons made from incredibly durable aluminum alloy for both strength and longevity in the face of massive torque and horsepower. The skirt of Wiseco pistons comes in a unique profile to help eliminate piston rock and also has an ArmorGlide coating that increases lubrication. When paired together, these two features help the big bore piston run as efficiently as if it was stock.
