CP Piston BRS Bore 4.030 Stroke 4.100 Rod 6.250 Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, part number BF6067-030. These pistons are built for serious engine builds where strength and reliability under high stress are paramount. With a bore size of 4.030 inches, a stroke of 4.100 inches, and a rod length of 6.250 inches, they are designed for specific performance engine configurations, often found in racing or heavily modified street applications. CP Pistons are well-known for their robust construction, using high-grade aluminum alloys to withstand the extreme pressures and temperatures generated in high-performance V8 engines.

The BRS series pistons are forged, meaning the aluminum is heated and then shaped under immense pressure. This process creates a much denser and stronger grain structure compared to cast pistons, making them far more resistant to deformation and failure when subjected to high cylinder pressures, such as those from forced induction or high compression ratios. The specific dimensions provided – 4.030" bore, 4.100" stroke, and 6.250" rod length – indicate these are intended for a particular engine blueprint, likely a stroker V8 where increased displacement and torque are the goals. These pistons are made to order and are non-cancelable, so it's important to confirm your engine specifications before purchasing.

This set includes all eight pistons needed for a V8 engine. Because these are custom-made, they are not CARB approved and cannot be shipped to California. It's always recommended to consult with your engine builder or refer to detailed engine build specifications to ensure these pistons are the correct choice for your specific application. Proper installation and balancing are critical for optimal performance and longevity.
