Mahle MS Piston Set BBC 540ci 4.500in Bore 4.25in Stroke 6.385in Rod 0.990 Pin -3cc 9.4 CR Set of 8

If you're building a high-performance Big Block Chevy engine, especially a 540 cubic inch stroker, getting the right pistons is crucial for power and reliability. This Mahle MS Piston Set is designed for those serious engine builds, offering a solid foundation for your project.

These pistons are forged from 4032 aluminum, a material known for its strength and durability, making them well-suited for the demands of a performance engine. They feature a flat-top design with a -3.4cc volume, which, when combined with the specified stroke and rod length, helps achieve a 9.4:1 compression ratio. This compression ratio is a popular choice for naturally aspirated or forced induction applications, offering a good balance between power and pump gas compatibility. The pistons come with a 0.990 inch pin, a standard size for many performance connecting rods.

This set includes eight pistons, enough for a complete V8 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning.
