CP Piston BRS BBC 4.625 Bore 4.375 Stroke 6.535 Rod Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP Pistons are built for serious big block Chevy performance builds. The material choice here is important; 2618-T61 is known for its strength and durability under high stress, making it a solid option for engines that will see heavy use or high horsepower. This set is specifically configured for a 4.625 inch bore with a 4.375 inch stroke, and uses a 6.535 inch connecting rod. This combination is a common setup for many high-performance big block applications, allowing for a good balance of displacement and piston speed.

CP Pistons is a well-known name in racing circles, and this set reflects their focus on robust construction. The pistons are designed to handle the demands of boosted or naturally aspirated performance engines. Because these are made to order, you're getting a set that's built specifically for this configuration, ensuring precise tolerances. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to CP Pistons' detailed specifications for proper installation and ring gap settings, as these are critical for engine longevity and performance.

This set includes eight pistons, enough for a complete V8 engine. Remember that when building a high-performance engine, attention to detail is key. Ensure all supporting components, such as rings, pins, and connecting rods, are compatible and meet the demands of your build. Since these are made to order, please allow for production time, and be aware that they are non-cancelable once the order is placed.
