The Bullet Piston LS1/LS2 4.020/4 Inch Stroke Dish -14.5 is a high-performance piston designed for GM's LS-series engines. It features a bore size of 4.020 inches and is intended for engines with a 4-inch stroke, making it suitable for both LS1 (5.7L) and LS2 (6.0L) V8 applications. The piston has a dish-shaped top, which helps optimize combustion characteristics, and the -14.5 cc dish volume helps lower the engine's compression ratio. This piston is ideal for performance and racing builds, allowing for more precise control over compression and air/fuel mixture, improving overall engine efficiency and power output.
