LS PowerPak Piston Set 4.005 Bore -5..8cc

The LS PowerPak Piston Set 4.005 Bore -5.8cc from MAHLE PISTONS is designed for serious LS engine builders and high-performance enthusiasts looking for reliable internal components. This piston set is essential for any LS platform build, whether for naturally aspirated or forced induction applications.

Engineered with precision, the 4.005-inch bore specification accommodates .005-inch overbore cylinders, enhancing displacement and ring sealing integrity. The -5.8cc dish design effectively lowers the compression ratio, making it suitable for high-boost applications. MAHLE's advanced casting techniques minimize piston rock and friction, which can lead to improved fuel economy and extended ring life.

This piston set is ideal for LS engine builds requiring overbore clearance, including LS1, LS2, LS3, and LSA applications. Proper installation requires precise honing and ring gap measurement to ensure optimal performance. With these pistons, builders can achieve the durability and consistency necessary for demanding engine builds.
