CP Piston Bullet Race Series Chevy LS1 15/L92 3.905 Bore 1.300 Ch 9.0:1 68 Head CC -9.7 CC Set Of 8

If you're building a high-performance Chevy LS1 or L92 engine, getting the right pistons is crucial for power and reliability. These CP Pistons Bullet Race Series pistons are forged from strong aluminum to handle the demands of a serious build. They're designed for a 3.905-inch bore and feature a 9.0:1 compression ratio, which is a popular choice for naturally aspirated or forced induction setups where you want a good balance of power and pump gas compatibility.

CP Pistons uses a forged manufacturing process, which creates a denser, stronger piston than cast or hypereutectic designs. This makes them much more resistant to detonation and the high cylinder pressures found in performance engines. The Bullet Race Series is known for its well-built construction and attention to detail, ensuring each piston is consistent. The 1.300-inch compression height is a key measurement that determines how the piston sits in the cylinder relative to the crankshaft, and these are specifically sized for common LS engine configurations with 68cc combustion chambers, resulting in a -9.7cc dish volume for that 9.0:1 compression target.

This set includes eight pistons, rings, wrist pins, and locks, so you have everything needed to install them. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to ensure your engine build is successful.
