Upgrade your Big Block Chevy engine with the Sportsman Racing Products 139832 high-compression forged domed piston set. Designed for performance-oriented BBC applications, this set includes eight pistons engineered to support increased compression and dependable operation under demanding conditions. The domed crown and precision-forged construction provide a strong foundation for high-performance engine builds while maintaining the fit and specifications required for compatible Big Block Chevy applications.
The Sportsman Racing Products 139832 pistons feature a 4.310 in bore size and a 1.270 in compression height, making them suitable for builds designed around these specifications. The dome volume is rated at +43.00 cc, helping builders select the appropriate piston configuration for their target compression ratio and combustion chamber combination. Always verify deck height, chamber volume, valve relief requirements, and final piston-to-valve clearance before assembly.
Each piston is machined with 1/16 in, 1/16 in, and 3/16 in ring grooves to accommodate compatible performance piston ring sets. The forged design is suited to engines requiring durable components and consistent dimensional control. This eight-piece set is a practical choice for rebuilding or assembling a high-compression Big Block Chevy engine where bore size, compression height, dome volume, and ring package compatibility are essential considerations.
