CP Piston BRS Big Block 4.560 Bore 4.250 Stroke 6.385 Rod 1.275 Set Of 8 (MTO Non-Cancel)

These CP Pistons BRS series pistons are built for big block engines, featuring a 4.560 inch bore and designed to work with a 4.250 inch stroke and a 6.385 inch rod length. The 1.275 inch compression height is a key measurement that determines how the piston sits in the cylinder bore relative to the deck surface, impacting compression ratio and valve clearance. This set includes eight pistons, ready for your high-performance build.

CP Pistons uses a proprietary BRS (Big Rig Series) forging process, which results in a well-built piston that can handle significant stress. The material is a strong, lightweight aluminum alloy chosen for its ability to withstand high temperatures and pressures common in performance applications. Each piston is machined to tight tolerances to ensure a precise fit and optimal performance. This is a made-to-order item, meaning it's built specifically for your order, so please allow for production time and note that these cannot be canceled once ordered.

When building a performance big block, the details matter. These pistons are designed to be a solid option for builders looking for reliable components. Because they are made to order, you're getting a fresh set built to the specified dimensions. Remember that this set is not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional for specific installation requirements and compatibility with other engine components.
