CP Piston Bullet Race Series Gen3 Dodge Hemi 3.937 Bore 4.050 Stroke 6.125 Rod Set Of 8

This is a set of eight CP Pistons Bullet Race Series Gen3 pistons, designed for Dodge Hemi engines. You get the pistons themselves, ready to be installed in your build. These are forged from aluminum, a strong material that's also lightweight, which is important for high-performance engines where reducing rotating mass can make a big difference. They feature a 3.937-inch bore and a 4.050-inch stroke, with a 6.125-inch rod length, making them a specific fit for certain Hemi engine configurations.

CP Pistons is a well-known name in racing circles, and this Bullet Race Series is built for demanding applications. The forged construction means these pistons can handle the higher cylinder pressures and temperatures that come with performance engine builds, like those found in modified Hemi engines. The 0.020 inch undersize specification means these pistons are machined to be slightly smaller than standard, which is common when rebuilding or modifying an engine to ensure proper clearance and fit within the cylinder bore. It's crucial to ensure your machine shop is aware of this specific sizing when preparing your engine block.

When you're building a serious Hemi engine, the pistons are a critical component. These CP Pistons are a solid option for those looking to get the most out of their Dodge Hemi. Remember, these are not CARB approved and cannot be shipped to California. Always consult with your engine builder or machine shop to confirm these pistons are the right choice for your specific engine build and to ensure proper installation procedures are followed.
