BBC Dome Piston Set 4.165 Bore +17cc

The BBC Dome Piston Set 4.165 Bore +17cc from ICON PISTONS is designed for high-performance big-block Chevy builds, focusing on enhancing compression ratio and combustion efficiency. This piston set is ideal for serious engine builders and mechanics aiming to maximize horsepower and torque in both naturally aspirated and forced-induction applications.

Featuring a +17cc dome chamber, these pistons increase compression while optimizing flame travel and fuel burn characteristics. ICON PISTONS utilizes premium hypereutectic or forged aluminum alloy for these components, ensuring thermal stability and durability under extreme cylinder pressures. The design of the piston skirt and pin boss architecture minimizes friction while maintaining rigidity, which is crucial for high-RPM operation and thermal cycling.

This BBC Dome Piston Set works best in big-block Chevy engines that require an increased compression ratio without necessitating custom head work or modifications to deck height. It is particularly beneficial for street performance, drag racing, or stroker builds where every cubic centimeter contributes to peak output.
