CP Piston BRS SB Chrysler Bore 4.080 Stroke 4.00 Rod 6.123 Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically made for Chrysler Small Block (SB) engines. These pistons feature a 4.080 inch bore, a 4.00 inch stroke, and are designed to work with a 6.123 inch connecting rod. CP Pistons are known for their robust construction, and these are built to handle the demands of a performance or heavily modified engine. Because they are made to order, you can be confident you're getting a fresh set built to precise specifications, though please note that once ordered, they cannot be canceled.

Forged pistons like these are a significant upgrade over cast pistons. The forging process aligns the metal's grain structure, making them much stronger and more resistant to detonation and fatigue under high cylinder pressures. This strength is crucial for engines that see aggressive use, high compression ratios, or forced induction like turbochargers or superchargers. The specific dimensions – 4.080 bore, 4.00 stroke, and 6.123 rod length – are common in many popular Chrysler SB performance builds, allowing for a good balance of displacement and piston speed. CP Pistons typically include high-quality wrist pins and wire locks, but it's always a good idea to confirm what's in the box for your specific part number.

When rebuilding or significantly upgrading your Chrysler SB engine, pistons are a critical component. These CP Pistons offer a well-built foundation for serious power. Remember that these pistons are made to order and are non-cancelable, so ensure they are the correct specification for your build before purchasing. They are not CARB approved and cannot be shipped to California.
