CP Piston Bullet Race Series Chevy LS2 4.005 Bore 4.125 Stroke 6.125 Rod 9.2 Set Of 8

Forged from 2618-T61 aluminum, these CP Pistons Bullet Race Series pistons are built for serious performance in Chevy LS2 engines. This set is designed for a 4.005 inch bore, a 4.125 inch stroke, and uses a 6.125 inch connecting rod, with a compression height of 1.575 inches to achieve a 9.2:1 compression ratio when paired with a 68cc combustion chamber. The 2618-T61 alloy is known for its strength and durability under high stress, making it a solid choice for demanding builds where reliability is key.

Each piston in this set features a full-floating wrist pin design, which allows for independent movement between the piston and the pin, reducing stress on both components during operation. The skirts are designed with a skirt coating to help reduce friction and noise, contributing to a smoother running engine. This set includes eight pistons, eight wrist pins, and eight sets of spiral locks, providing everything you need to outfit your LS2 engine for a performance rebuild. The 4.005 inch bore size is a common upgrade for LS2 engines looking to increase displacement and power.

When rebuilding your LS2 with these pistons, ensure you have the correct connecting rods and crankshaft to match the specified dimensions. Proper balancing of the rotating assembly is also crucial for longevity and performance. These pistons are intended for race applications and high-performance street use where increased power output is desired.
