Overview

The UEM Piston GM 6.0L 4.010/STD Stroke Flat is a high-performance piston designed for GM 6.0L LS-based engines, offering increased displacement and improved combustion efficiency. With a 4.010-inch bore, it provides a slight overbore, ideal for engines that need a rebuild or are being prepared for performance upgrades. The flat-top design allows for optimal combustion, helping to increase compression ratios depending on the specific setup of the engine, such as the cylinder head and gasket used. This piston is designed to be compatible with the standard stroke crankshaft, ensuring OEM stroke specifications are maintained for balanced engine performance. Made from high-quality materials, it’s engineered to withstand high temperatures and pressures, making it suitable for both naturally aspirated and forced induction applications. Whether used for street performance, motorsport, or high-horsepower builds, the UEM piston delivers the strength and efficiency required to handle demanding conditions while improving overall engine output.
