CP Piston BRS Big Block 4.625 Bore 4.250 Stroke 6.535 Rod 1.120 Set Of 8 (MTO Non-Cancel)

When you're building a serious big block engine, the pistons are the heart of the operation. This set from CP Pistons is designed for high-performance applications where strength and reliability are paramount. These aren't just off-the-shelf parts; they're made-to-order to ensure they meet the exact demands of your custom engine build.

This specific set features a 4.625 inch bore and a 4.250 inch stroke, paired with a 6.535 inch rod length. The 1.120 inch compression height is crucial for achieving the desired deck clearance and compression ratio with your chosen crankshaft and connecting rods. CP Pistons uses advanced forging techniques to create pistons that are incredibly strong and lightweight, which helps reduce reciprocating mass and allows the engine to rev more freely. This set includes eight pistons, enough for a complete V8 engine.

Because these pistons are made-to-order, they offer a unique opportunity to tailor your engine's internals precisely. Please note that due to their custom nature, these pistons are non-cancelable once ordered. Also, they are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
