CP Piston & Ring for Chevrolet Small Block - Bore (4.030in) - Rod (5.700in) - CR (10.5:1) - Set of 8

This is a set of eight forged pistons and rings from CP Pistons, specifically made for Chevrolet Small Block engines. You get everything needed to outfit all eight cylinders with pistons and their matching rings, ready for installation. These are designed for a 4.030-inch bore and use a 5.700-inch rod length, resulting in a 10.5:1 compression ratio. This setup is a popular choice for builders looking to increase the performance and durability of their engine, especially when rebuilding or upgrading the top end.

CP Pistons are well-known in the performance engine building community for their robust construction and attention to detail. These pistons are forged from high-strength aluminum alloy, which makes them significantly stronger and more resistant to detonation and fatigue compared to cast pistons. This strength is crucial for engines that will see higher cylinder pressures, increased boost, or aggressive tuning. The specific compression ratio of 10.5:1 is a good balance for many performance applications, offering a noticeable power increase over stock while still being manageable with premium pump gasoline in many setups. The included rings are designed to work seamlessly with the pistons, ensuring a good seal for optimal compression and oil control.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Because these are performance components, they are often paired with upgraded connecting rods and crankshafts to handle the increased power output. Please note that this piston set is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation guide for precise specifications and recommended practices.
