CP Piston BRS Chevy LS7 4.135 Bore 4.125 Stroke 6.125 Rod Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from 2618 aluminum, a strong material chosen for its ability to handle high temperatures and pressures without deforming. This set is specifically built for Chevy LS7 engines, featuring a 4.135-inch bore and a 4.125-inch stroke, designed to work with a 6.125-inch connecting rod. This combination is key for achieving the desired displacement and performance characteristics in a performance build.

The BRS series pistons are designed with a specific skirt profile and ring land configuration to optimize performance and durability in demanding applications. Each piston in this set of eight is meticulously machined to ensure consistent weight and dimensions, which is crucial for engine balance and smooth operation at high RPMs. The 0.010-inch undersize specification means these pistons are slightly smaller than standard, intended for engines that may have been previously bored or require a specific clearance for optimal piston-to-wall fit.

When building a high-performance LS7, attention to detail in component selection makes a significant difference. These pistons are a solid option for enthusiasts looking to rebuild or upgrade their engine with well-made components.
