GM LS Dished Piston Set 4.030 Bore -10cc

The GM LS Dished Piston Set 4.030 Bore -10cc from Race Tec Pistons is designed for serious LS engine builders and high-performance enthusiasts. This piston set helps maximize compression ratios and combustion efficiency in both naturally aspirated and boosted applications. Its dished design allows for precise compression tuning, making it suitable for competitive racing and high-performance builds.

The -10cc dish geometry reduces the piston dish volume by 10 cubic centimeters per cylinder, enabling builders to achieve specific compression ratios based on head selection, gasket thickness, and stroke combination. Race Tec Pistons manufactures these components to OEM-grade tolerances, ensuring a consistent fit across all eight cylinders and reliability under high RPM operation. The 4.030-inch bore specification is compatible with LS1, LS3, LS7, and LQ4 blocks, providing versatility across various LS engine families.

This piston set is ideal for professional machine shops, engine rebuilders, and track-focused enthusiasts looking to enhance performance. With premium forging processes and thermal treatments, these pistons deliver the strength necessary for both naturally aspirated engines producing 500+ horsepower and forced-induction builds exceeding 1,000 hp with the right supporting components.
