What is the compression ratio with these pistons?

The compression ratio depends on the cylinder head volume, head gasket thickness, and deck height of your specific engine build. The flat-top design allows for flexibility in achieving your target compression ratio.

What connecting rods are compatible with these pistons?

These pistons use a .945 inch wrist pin, which is a common size for many performance connecting rods used in Chevrolet LS engines. Always verify compatibility with your chosen connecting rod manufacturer.

Are these pistons suitable for a supercharged or turbocharged engine?

Yes, these are forged pistons designed for high-performance applications, which typically include forced induction setups like superchargers or turbochargers. Their robust construction helps them withstand the increased cylinder pressures.

Product Details

These are Carrillo Bullet Series forged pistons specifically made for Chevrolet LS series engines. They feature a 4.005-inch bore and a flat-top design, paired with a .945-inch wrist pin. If you're building a high-performance LS engine, these pistons are a solid choice for handling increased power and stress.

Carrillo is well-known for making strong internal engine components, and these pistons are no exception. They are forged from a high-strength aluminum alloy, which gives them the durability needed for demanding applications. The flat-top design is ideal for many naturally aspirated or forced induction builds, allowing for precise control over compression ratios when paired with the right cylinder heads and head gaskets. The .945-inch pin is a common size for many performance LS applications, making them compatible with a wide range of connecting rods.

When you're assembling a performance engine, the quality of the rotating assembly is critical. These Carrillo pistons are built to withstand the rigors of competition or serious street use. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, especially regarding ring gap and piston-to-wall clearance.
