SBC Flat Top Piston Set 4.040 Bore w/Rings

The SBC Flat Top Piston Set 4.040 Bore w/Rings from KB Performance Pistons is designed for small-block Chevrolet builders and engine enthusiasts looking to enhance performance. This piston set is particularly suitable for stroker builds and high-RPM applications where optimizing compression ratios and ensuring valve-to-piston clearance are essential.

Engineered for durability and performance, the flat-top design minimizes piston-to-cylinder head interference, making it ideal for aggressive cam profiles and ported heads. The 4.040-inch bore allows for increased displacement while maintaining structural integrity, especially in forced-induction and naturally aspirated engines. The included piston rings are designed to ensure proper sealing and reduce blow-by during high-load operation.

This piston set is perfect for those building dedicated track engines or restoring classic Chevys with modern performance in mind. With its optimized design, it provides the reliability and performance characteristics that serious engine builders demand, making it a valuable addition to any high-performance engine project.
