LS FT Piston Set 3.790 Bore -4.2cc

The LS FT Piston Set 3.790 Bore -4.2cc from Wiseco is designed for high-performance LS engine builds, catering to both automotive enthusiasts and professional engine builders. This piston set is ideal for those developing naturally aspirated strokers or aiming for significant power in forced-induction setups.

Engineered with precision, these forged LS pistons feature a 3.790-inch bore diameter and a -4.2cc compression cavity, allowing tuners to achieve precise compression ratios tailored to their fuel and boost levels. The negative compression volume is essential for managing detonation in turbocharged or supercharged applications while ensuring optimal combustion efficiency.

Wiseco's reputation for quality ensures that these pistons can withstand the extreme demands of competition engines and high-RPM track builds. Compatibility with various LS block variants (Gen III/IV LS1, LS2, LS3, LSA, LS7, or 6.2L) requires verification of connecting rod length for proper fitment, making this piston set a versatile choice for serious performance applications.
