The S-21B Pistons 302 21B Racing Patterson 030 are a high-performance upgrade for your racing engine. These pistons are designed specifically for the 302 cubic inch engine and are part of Patterson's S-Series line, which is known for its exceptional strength and durability.
The S-21B pistons are forged from 2618-T6 aluminum alloy, a material chosen for its superior strength and heat resistance. The piston crown is dish-shaped, with a compression ratio of 12.5:1, which is ideal for high-performance applications. The skirt is full-floating, which reduces friction and allows for increased power output.
The piston rings are made from chrome molybdenum steel, which is known for its durability and ability to withstand high temperatures and pressures. The top ring is a multi-lobed design, which helps to prevent oil consumption and improve combustion efficiency. The second and third rings are also full-floating, which reduces friction and helps to prevent ring groove damage.
The S-21B pistons also feature a high-silicon skirt coating, which helps to reduce friction and increase cylinder wall lubrication. This coating is applied using a plasma spray process, which ensures a consistent and even application.
In addition, these pistons come with a precision-machined pin bore, which ensures proper alignment of the connecting rod and piston pin. The pin bore is also chamfered, which helps to reduce wear and improve oil flow.
Overall, the S-21B Pistons 302 21B Racing Patterson 030 are a high-quality upgrade for your racing engine. They are designed to withstand the high temperatures and pressures of racing, while also providing improved performance and efficiency. Whether you're looking to increase horsepower, improve fuel economy, or simply upgrade your engine, these pistons are a great choice.
