Overview

The Bullet Pistons BLS1009-007P is a piston and ring set designed for GM LS-Series engines. Crafted from forged aluminum, these pistons offer enhanced strength and durability for high-stress applications. The flat top design promotes combustion efficiency, while the 3.905-inch bore diameter and 1.110-inch compression height are suitable for performance upgrades and custom builds.

This set features 1.5 mm ring grooves for the top and second compression rings, ensuring proper sealing. The pistons include a -2.70 cc dish, which helps achieve optimal compression ratios in various setups. Bullet Pistons provides these components as a reliable foundation for high-performance engine assemblies, delivering quality that meets demanding specifications.
