CP Piston BRS Chevy 403Ci Ascs 4.135 Bore 1.125 Ch 8CC Dome - Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP Pistons BRS series pistons are built for serious performance builds, specifically for Chevy 403ci applications. The 4.135-inch bore size is a common starting point for many stroker or big-bore engine builds, and the 1.125-inch compression height works with a variety of crankshafts to achieve your desired deck height and compression ratio. The 8cc dome volume is designed to work with specific cylinder head chamber volumes to fine-tune your engine's compression.

CP Pistons is known for their well-built components, and this set is no exception. The 2618-T61 aluminum alloy offers a good balance of strength and thermal expansion properties, making it suitable for high-performance street or track use. These pistons are made to order, meaning they are manufactured specifically for your purchase, which ensures you're getting a fresh, high-quality set. Because they are custom-made, please note that these are non-cancelable once ordered.

This set includes eight pistons, rings, and wrist pins, ready for installation into your 403ci Chevy engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted professional for specific recommendations regarding piston-to-wall clearance, ring gap, and assembly procedures to ensure optimal performance and longevity for your build.
