GM LS FT Piston Set 4.070 Bore -3.3cc

The GM LS FT Piston Set 4.070 Bore -3.3cc by Race Tec Pistons is a precision-engineered solution for LS engine builders and performance enthusiasts. It is designed for those seeking reliable, high-quality internals for naturally aspirated or moderately boosted applications. This piston set is ideal for stock or lightly overbored GM LS-platform engines, providing an accessible upgrade path without requiring extensive block work.

Manufactured using premium aluminum alloy forging techniques, these pistons deliver superior strength-to-weight ratios critical for high-RPM durability. The -3.3cc dish reduces compression volume, allowing builders to optimize compression ratios when pairing these pistons with modern cylinder heads or when running forced induction. This design also improves quench clearance and helps manage detonation, promoting efficient combustion chamber dynamics.

Builders working on LS1, LS2, LS6, or truck-based 5.3L and 6.0L platforms will find this piston set compatible with standard LS rotating assemblies. With a full V8 set of 8 pistons, this product is perfect for those looking to push their LS engines beyond factory parameters while maintaining reliability and performance.
