SBC Custom FT Piston Set 4.160 Bore

The SBC Custom FT Piston Set 4.160 Bore from JE PISTONS is designed for serious small-block Chevrolet builders who require precision-forged reliability for high-performance and racing applications. This piston set is ideal for those constructing street engines, bracket racers, or boost-prepped platforms, delivering the strength and dimensional accuracy necessary to withstand aggressive combustion events and high RPMs.

Featuring JE's proprietary FT (Forged Technology) construction, these pistons optimize material flow and eliminate weak points often found in cast designs. The 4.160-inch bore specification is specifically engineered for overbored small-block applications, allowing for increased displacement and horsepower while maintaining tight tolerances that are crucial for ring seal and longevity. The precise weight matching of the piston set ensures balanced reciprocating assembly dynamics, which reduces vibration and extends engine life.

This piston set is perfect for engine builders, performance shops, and enthusiasts who are rebuilding SBC blocks (265–400 cubic inches) with overbore specifications. JE's advanced cooling galleries and pin design efficiently dissipate heat, preventing detonation-induced failures in high-compression or nitrous-assisted builds. With these features, the SBC Custom FT Piston Set is a trusted choice for those pushing the limits of performance.
