SBC Dome Powerpak Piston Set 4.040 Bore +12cc

The SBC Dome Powerpak Piston Set 4.040 Bore +12cc from MAHLE is designed for small-block Chevrolet engine builders who seek reliable performance for both street and strip applications. This piston set is ideal for enthusiasts looking to enhance their modified or stock-based SBC builds, providing the necessary components for high-performance engines.

Constructed with precision forging and advanced metallurgy, this piston set ensures durability and tight tolerances. The dome design increases chamber volume efficiency, which is critical for managing detonation in high-compression applications. The +12cc dome volume is essential for calculating final compression ratios when paired with specific block and head combinations.

This piston set is particularly beneficial for those tuning street engines or building bracket racing platforms. The 4.040-inch bore size accommodates specific overbore applications, allowing for enhanced displacement. With premium skirt coatings and hardened wrist pins, this set minimizes friction and extends service life under aggressive driving conditions.
