About this part

Product Details

Forged from 2618-T61 aluminum, these CP Pistons are built for serious performance in your Chevy LS2 engine. The 4.030 inch bore size is a common upgrade for LS2 blocks, allowing for increased displacement when paired with a 3.9 inch stroke crankshaft and 6.125 inch connecting rods. This specific combination results in a compression ratio of 11.1:1, which is well-suited for naturally aspirated builds or those using moderate boost. The 2618-T61 aluminum alloy offers a good balance of strength and thermal expansion properties, making it a reliable choice for high-performance applications where heat and pressure are significantly higher than stock.

These pistons are manufactured as a set of eight, ensuring consistent performance across all cylinders. The MTO (Made To Order) designation means these pistons are produced specifically for your order, so please allow for production time and note that they cannot be canceled once the order is placed. This level of customization and build quality is what you expect when pushing the limits of your engine. They are designed to work with a 6.125 inch connecting rod, a popular length for many LS engine builds that helps achieve optimal piston-to-wall clearance and ring land integrity.

When building a high-performance LS2, choosing the right internal components is critical. These CP Pistons are a solid option for anyone looking to upgrade their engine's rotating assembly for increased power and durability. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer specifications for complete compatibility and installation details.
