GM LS Dished Piston Set 4.125 Bore -6cc

The GM LS Dished Piston Set 4.125 Bore -6cc from RACE TEC PISTONS is a forged eight-piece piston set specifically engineered for General Motors LS-series engine builds. This piston set is ideal for applications that require precise compression control and optimized combustion chamber geometry, particularly in supercharged, turbocharged, or nitrous oxide setups.

Featuring a negative 6cc dish cavity, this piston set delivers reduced compression ratios essential for managing boost pressure and maintaining stable detonation characteristics. The 4.125 inches bore diameter is tailored for LS stroker builds and large-displacement variants, ensuring strength and durability under high-boost conditions. The forged construction minimizes the risk of crown failure or ring land collapse, making it suitable for aggressive ignition timing.

Builders working with LS engine platforms, whether for street performance or racing, can rely on RACE TEC PISTONS for components that withstand extreme cylinder pressures and thermal cycling. This piston set is designed to support power targets from moderate turbo builds to extreme forced-induction applications, provided that proper ring selection and fuel optimization are implemented.
