The Manley 6667M85AP 85mm Wisco Pistons are a high-performance upgrade for your engine, specifically designed for high-compression applications. These pistons are crafted by Wisco, a renowned manufacturer known for their precision and quality.
Each piston is made from forged 2618-T6 aluminum alloy, ensuring superior strength and durability. The 85mm bore diameter is suitable for larger engines that require increased power and torque. The piston skirts are honed to a mirror finish for minimal friction, which contributes to improved engine efficiency and reduced heat buildup.
The Manley 6667M85AP pistons feature a dish shaped crown, which is designed to work in conjunction with high-lift camshafts. This design allows for increased valve lift, resulting in improved volumetric efficiency and power output. The piston tops are also designed with an octane friendly compression ratio of 13.5:1, making them ideal for high-octane fuel.
The pistons come with fully floating wrist pins and low-tension rings. The wrist pins are made from high-strength steel and are precision-machined to provide a snug fit in the pin bore. The low-tension rings are designed to reduce friction and prevent ring groove distortion, thereby extending the life of the pistons.
The Manley 6667M85AP 85mm Wisco Pistons are a top choice for engine builders and enthusiasts who demand the best in terms of performance, reliability, and quality. They are a direct replacement for stock pistons and can be easily installed with standard tools.
