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

The Wiseco GM LS F/T Piston & Ring Set 4.070 Bore -11cc (K444X7) is a professional-grade forged piston and ring kit engineered for high-performance GM LS-series engine builds. This complete piston and ring set delivers the precision and durability required for forced-induction applications, street performance builds, and competitive racing environments where engine reliability under sustained load is non-negotiable.

The 4.070-inch bore specification accommodates oversized displacement builds common in LS engine modifications. The -11.00 cubic centimeter dish in the piston crown reduces compression volume, allowing builders to tune compression ratio for forced-induction setups or premium fuel requirements. Ring grooves are precisely machined at 1.2 x 1.2 x 3.0 millimeter dimensions, ensuring optimal ring seal and minimal blowby across the rpm range. Wiseco's forged construction provides superior strength compared to hypereutectic designs, critical for high-boost applications and elevated engine speeds where piston durability directly impacts long-term reliability.

This kit is designed for serious LS engine builders and performance enthusiasts constructing turbocharged, supercharged, or naturally aspirated stroker platforms. Whether assembling an engine for sustained track use, street performance with occasional boost, or competition duty, this piston and ring set provides the engineering and material quality necessary for dependable power delivery. The complete kit eliminates the complexity of sourcing compatible components separately, streamlining the build process while ensuring all critical tolerances align for proper installation and operation.
