SBC Domed Piston Set 4.060 Bore +13.7cc

The SBC Domed Piston Set 4.060 Bore +13.7cc from JE PISTONS is engineered for serious small block Chevy builders seeking high-compression performance and reliable top-end durability. This forged piston set addresses the specific demands of stroker builds, nitrous applications, and high-RPM racing where chamber geometry and compression ratio directly impact power output and engine longevity. Each set contains eight pistons precisely matched for consistent combustion and minimal variation across all cylinders.

Built from premium forged aluminum, the domed design adds 13.7cc of displacement to the combustion chamber, raising compression ratio and promoting more efficient fuel burn—critical for extracting maximum power from forced-induction and naturally-aspirated builds alike. The 4.060-inch bore accommodates modern overbore blocks while the precisely engineered ring grooves (1/16 x 1/16 x 3/16 inch) ensure proper ring seating and minimize blowby. JE's forged construction delivers exceptional strength under extreme cylinder pressures, thermal stability across wide temperature ranges, and resistance to detonation and mechanical failure that cast alternatives cannot match.

This piston set is ideal for small block Chevy engine builders planning high-compression stroker builds, nitrous oxide injection systems, supercharger applications, or competition racing where reliability and power density are non-negotiable. Proper installation requires matching rod lengths, accurate deck height measurement, and verification of piston-to-valve and piston-to-block clearances specific to your cylinder head and intake manifold combination. Pairing these pistons with quality rings, pins, and connecting rods ensures the foundation for a potent, long-lasting small block engine.
