CP Piston Bullet Race Series Small Block Chevy 4.125 Bore 4.000 Stroke 6.000 Rod Set Of 8

Forged from 2618-T61 aluminum, these CP Pistons Bullet Race Series pistons are built for serious Small Block Chevy performance builds. The 2618-T61 alloy is known for its strength and ability to withstand high temperatures and pressures, making it a solid choice for racing applications where durability under extreme conditions is paramount. This set is designed for a 4.125 inch bore, a 4.000 inch stroke, and uses a 6.000 inch connecting rod, a common configuration for many high-performance Small Block Chevy engines.

Each piston in this set of eight features a deep valve relief to accommodate larger camshaft profiles without interference, a critical detail when building a custom performance engine. The skirt design is optimized for reduced friction and improved piston-to-wall contact, contributing to better ring seal and overall engine efficiency. CP Pistons also includes high-quality wrist pins with this set, ensuring a strong connection between the piston and connecting rod. These pistons are intended for use in competition engines where maximum performance and reliability are required.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and procedures. Because these are performance pistons, they are not CARB approved and cannot be shipped to California. Always consult the detailed installation instructions provided by CP Pistons for the best results and to ensure proper engine assembly.
