LS FT Powerpak Piston Set 4.125 Bore -4.0cc

The LS FT Powerpak Piston Set 4.125 Bore -4.0cc from MAHLE PISTONS is designed for serious LS engine builders and performance enthusiasts focused on high-compression builds and naturally aspirated power gains. This forged piston set is essential for maximizing cylinder pressure while ensuring structural integrity during high-RPM operation.

With a bore diameter of 4.125 inches and a -4.0cc dish geometry, these pistons optimize compression ratios and quench clearance, which are crucial for detonation control and combustion efficiency. The forged construction and premium material chemistry allow these pistons to withstand the thermal and mechanical stresses associated with modified LS engines.

Ideal for applications such as street engines, weekend warriors, or turbocharged platforms, this piston set is compatible with LS1, LS2, LS3, and other LS-based variants. The precise manufacturing tolerances ensure a proper fit within cylinder walls, minimizing blow-by and enhancing oil control ring performance.
