GM LS F/T Piston & Ring Set 4.070 Bore -11cc

The Wiseco GM LS F/T Piston & Ring Set 4.070 Bore -11cc is engineered for serious LS engine builds where precision engineering and proven reliability are essential. Designed specifically for high-performance applications, this forged piston and ring combination delivers the durability required in turbocharged, supercharged, and naturally aspirated LS platforms. Whether you're building a street machine, track weapon, or competition engine, Wiseco's reputation for quality construction makes this set the go-to choice for builders who demand consistent results across diverse power levels.

The -11cc compression height allows for precise control over your final compression ratio, which is critical when tuning boost levels or adapting to fuel octane requirements. Wiseco's forged aluminum pistons undergo rigorous metallurgy standards to handle detonation events and sustained high RPM operation without galling or skirt wear. The included ring set features optimized end gaps and tension profiles that accommodate thermal expansion while maintaining optimal sealing—essential in forced induction applications where cylinder pressures and temperature swings demand superior piston-to-cylinder wall dynamics.

This piston and ring set fits LS1, LS2, LS3, LS6, LS7, and LSx-based engines across generations, making it ideal for builders transitioning from stock engines to upgraded setups. The 4.070-inch bore specification ensures OEM-accurate sizing for LS platforms without the guesswork of custom sizing. With its robust design and high-performance capabilities, this set is perfect for enthusiasts looking to maximize their engine's potential.
