Wiseco forged piston kit designed for durability and high performance. Constructed from high-silicon aluminum alloy for maximum strength and reliability. Engineered for optimal heat transfer from the combustion chamber to the cylinder walls. The elliptical design provides a uniform bearing surface under heat expansion, preventing localized pressure and piston collapse. The precision-machined skirt features an Armor Glide coating for enhanced performance. This piston has an 8.3:1 compression ratio and an oversize bore of +0.50mm.
