SBC Dome Piston Set 4.185 Bore +13.5cc

The SBC Dome Piston Set 4.185 Bore +13.5cc from Wiseco is a precision-engineered solution tailored for small-block Chevrolet builders focused on high-compression performance builds. This piston set is ideal for engine enthusiasts and professional machine shops looking to enhance horsepower without sacrificing reliability.

Designed to optimize combustion chamber geometry, the +13.5cc dome volume effectively reduces the combustion chamber size, allowing for increased compression ratios that can unlock additional power. Manufactured from premium forged aluminum alloy, these pistons feature proprietary ring grooves and skirt coatings that ensure durability and performance under high-stress conditions.

Builders targeting compression ratios between 11:1 and 13:1 will find these pistons particularly beneficial, depending on chamber volume and stroke selection. The 4.185-inch bore specification guarantees a precise fit in standard SBC blocks, making them suitable for various applications, including street performance and competition engines.
