CP Piston Bullet Race Series Chevy LS2 Flat Top -3.8CC Afr LS3 12 4.030 Bore 1.300 Ch Set Of 8

Forged from 2618 aluminum alloy, these CP Pistons Bullet Race Series pistons are built for serious performance applications. The flat-top design features a -3.8cc dish, which is specifically calculated to work with LS3 cylinder heads and achieve a 12.4:1 compression ratio when used with a 4.030 inch bore and a .040 inch compressed head gasket. This precise compression ratio is key for maximizing power output in naturally aspirated or forced induction builds where every bit of efficiency matters.

Each piston is machined to a 4.030 inch bore size, a common upgrade for LS engines looking to increase displacement. The 1.300 inch compression height is also a critical measurement, ensuring proper piston-to-valve clearance and deck height with your chosen connecting rods and crankshaft. CP Pistons is known for their tight tolerances and robust construction, and this Bullet Race Series set is no exception. They are designed to handle the stresses of high-performance engines, offering a well-built solution for builders aiming for significant power gains.

This set includes eight pistons, enough for a full V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional to ensure these pistons are the correct choice for your specific build and to confirm all necessary components for installation.
