CP Piston Chevy LS 378ci / LS3/L92 4.095 Bore 1.300 CH 5.6cc Dome Piston Set - Set of 8

CP Pistons offers this set of eight forged pistons specifically for Chevy LS 378 cubic inch engines, including LS3 and L92 applications. These pistons are built to handle the demands of a performance-oriented engine rebuild, featuring a 4.095 inch bore and a 1.300 inch compression height. The 5.6cc dome volume is designed to work with specific cylinder head volumes to achieve a desired compression ratio.

Crafted from high-strength forged aluminum, these pistons are significantly more durable than cast pistons, making them a solid choice for boosted or high-compression naturally aspirated builds. The 0.010 inch undersize specification means these pistons are intended for engines that have been bored out to match this size, ensuring a proper fit within the cylinder walls. CP Pistons is known for producing well-built internal engine components that perform under pressure, and this set is no exception. They are designed to be a direct replacement for the factory pistons, assuming the block has been machined to the correct bore size.

When undertaking an engine rebuild of this caliber, it's important to ensure all supporting components are up to the task. These pistons are a critical part of the rotating assembly, and their strength and precise dimensions contribute to the overall reliability and performance of your LS engine. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or machine shop for specific installation requirements and recommended clearances.
