This Big Bore piston and cylinder set fits the Citroën 2CV6 model with a 77 mm diameter. The components replace the standard pistons and cylinders and fit in the original engine housing. The set supports increased cylinder capacity, which affects torque and power delivery. The material is selected for typical engine temperatures and mechanical loads in everyday use. The tolerances support reliable sealing between piston rings and cylinder wall. The set serves as a basis for engine service or overhaul and is compatible with existing components such as connecting rods and cylinder heads. It supports consistent operation within the original engine layout.
