CP Piston BRS SB Chrysler Bore 4.030 Stroke 4.000 Rod 6.123 Set Of 8 (MTO Non-Cancel)

This set includes eight forged pistons from CP Pistons, designed for Chrysler SB (Small Block) engines. Each piston has a bore size of 4.030 inches, a stroke of 4.000 inches, and a rod length of 6.123 inches. These pistons are made to order and are non-cancelable once production begins, so please confirm your application before ordering.

CP Pistons are well-known for their robust construction, and these forged units are built to handle the demands of performance engines. Forging is a process where aluminum is heated and shaped under extreme pressure, creating a denser, stronger, and more durable piston than cast alternatives. This makes them ideal for applications where increased cylinder pressures and higher operating temperatures are expected, such as modified street engines or racing applications. The specific dimensions provided—4.030" bore, 4.000" stroke, and 6.123" rod length—are critical for achieving the desired compression ratio and engine displacement when paired with the correct crankshaft and connecting rods.

Because these pistons are made to order, they are not eligible for cancellation or return once the manufacturing process has started. It's important to ensure these specifications precisely match your engine build requirements. Please note that this product is not CARB approved and cannot be shipped to California.
