CP Piston BRS Chevy 6.0L All LS Bore 4.000 Ch 1.304 Stroke 3.622 Rod 6.125 Set Of 8 (MTO Non-Cancel)

These CP Pistons are forged from high-strength aluminum, a material chosen for its excellent strength-to-weight ratio, which is crucial for high-performance engine builds. The specific alloy used here is designed to handle the extreme pressures and temperatures found in performance LS engines, particularly those based on the 6.0L platform. With a bore size of 4.000 inches, these pistons are intended for engines that have been machined to this specific dimension, often as part of a performance rebuild or stroker kit.

The design details matter for how these pistons perform inside your engine. The compression height is set at 1.304 inches, which dictates the piston's position in the cylinder bore relative to the wrist pin. This measurement, along with the 3.622-inch stroke and 6.125-inch rod length, is carefully calculated to achieve a specific compression ratio and piston-to-valve clearance when paired with the correct crankshaft and cylinder heads. This set includes eight pistons, ready to be installed in a V8 LS engine. Because these are made-to-order, they are non-cancelable, so be sure this is the exact specification you need for your build.

It's important to note 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, especially regarding ring gap, bearing clearances, and piston-to-wall clearance, which are critical for engine longevity and performance.
