( Brand: Je Pistons ), ( Manufacturer Part Number: 242892 ), ( Part Type: Rod ), ( Fitment Type: Performance/custom )
The 242892 JE 4.165 15.3 dome pistons for Chevy 400 engines are a high-performance upgrade for any enthusiast looking to enhance their engine's power and efficiency. These pistons are designed specifically for applications with a 23-degree valve angle and a 6.125-inch connecting rod length.
The 4.165-inch dome piston design provides excellent combustion chamber volume, allowing for optimal air-fuel mixture and combustion efficiency. The dome shape also helps to reduce detonation and increase engine longevity by reducing stress on the piston rings and cylinder walls.
The pistons are made from 2618-T6 aluminum alloy, which is known for its strength and durability. This alloy is heat-treated to ensure maximum strength and fatigue resistance, ensuring that the pistons can withstand the high temperatures and pressures generated by high-performance engines.
The pistons feature a 3.500-inch wrist pin bore, which allows for the use of high-performance wrist pins and rings. The pistons also feature a full-floating wrist pin design, which reduces friction and improves engine performance.
The 15.3-degree valve relief angle on these pistons provides optimal valve movement and reduces the risk of valve contact with the piston dome. This angle also helps to reduce the chance of piston-to-valve interference during engine operation.
Overall, the 242892 JE 4.165 15.3 dome pistons are a high-quality upgrade for any Chevy 400 engine looking to increase power and efficiency while also improving engine longevity. These pistons are designed to withstand the rigors of high-performance applications and will provide years of reliable service.
