CP Piston BRS Big Block 4.530 Bore 4.250 Stroke 6.385 Rod 1.275 Set Of 8 (MTO Non-Cancel)

CP Pistons is well-known for making high-performance internal engine components, and this BRS Big Block piston set is a prime example of their commitment to power and reliability. If you're building a serious big block engine, these pistons are designed to handle the demands of high-horsepower applications. They feature a 4.530 inch bore and are designed to work with a 4.250 inch stroke crankshaft, utilizing a 6.385 inch rod length. This specific set is for an 8-cylinder engine and is sized at 0.030 inches undersize.

These pistons are forged, which means they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see heavy use or high stress. The BRS series is engineered for robust performance, and CP Pistons pays close attention to details like ring land design and skirt profiles to ensure optimal combustion and reduced friction. The 1.275 inch compression height is a key measurement that dictates how the piston sits in the cylinder relative to the deck of the block, and it's critical for achieving the correct compression ratio with your chosen cylinder heads and crankshaft.

Because these pistons are made to order, they are non-cancelable once production begins. Please be aware that this part is not CARB approved and cannot be shipped to California. It's always a good idea to double-check all your engine dimensions and clearances before ordering custom internal components like these to ensure a perfect fit and optimal performance for your build.
