SBM 360 F/T Piston Set 4.060 Bore -5cc

The SBM 360 F/T Piston Set 4.060 Bore -5cc is a complete eight-piston assembly engineered for Small Block Mopar engine builders and restoration specialists seeking OEM-quality performance components. This KB Series piston set delivers the precision bore diameter and chamber volume required for high-compression small block applications, making it an essential upgrade for those rebuilding classic Mopar platforms or upgrading existing powerplants with improved durability and combustion efficiency.

Each piston in this set features a 4.060 inch bore diameter with precisely machined 5/64 x 5/64 x 3/16 inch ring grooves, designed to maintain strict tolerances and optimal ring sealing throughout the engine's operating range. The minus 5.00 cubic centimeter chamber volume creates a higher compression ratio, promoting more efficient fuel burn and improved power output without requiring extensive block modifications. The KB Series construction utilizes robust metallurgy and proven design geometry to withstand sustained high-RPM operation while maintaining dimensional stability and thermal control under demanding driving conditions.

Restoration shops, performance engine builders, and dedicated Mopar enthusiasts rely on the SBM 360 F/T Piston Set for rebuilds requiring exact factory specifications or controlled compression increases. The set of eight pistons ensures complete cylinder coverage for typical Small Block Mopar V8 configurations, eliminating the need for separate purchases. Installation requires standard engine building procedures with proper ring gap measurement and honing to specification for optimal sealing and longevity in both street and competition applications.
