SBC Dished Piston Set 4.030 Bore -31cc

The SBC Dished Piston Set 4.030 Bore -31cc from Sportsman Racing Products is designed for small-block Chevrolet engine builders focused on achieving lower compression ratios for high-performance forced induction applications. This piston set is particularly beneficial for those tuning for boost or optimizing fuel octane requirements in modified short blocks.

Featuring a -31cc dish volume, these pistons are constructed with precision-forged technology to ensure durability and strength under high-boost and extreme RPM conditions. The 4.030-inch bore accommodates oversized cylinder prep, making it suitable for competitive small-block builds where effective compression ratio management is crucial.

Engine builders working on LS or Gen III/IV small-block platforms will find this piston set advantageous for its compatibility with specific configurations that require lower compression. Each piston is designed with precision ring grooves and skirt coatings to minimize friction and enhance performance under load.
