Product Details
If you're building a high-performance Chrysler small block engine, getting the right pistons is a critical step. This set from CP Pistons is designed for serious builds where durability and precise fitment are paramount. These aren't your average off-the-shelf pistons; they're made to order to ensure they meet the exact specifications needed for your engine's rebuild or performance upgrade.
This particular set features a 4.070 inch bore, a 4.000 inch stroke, and is designed to work with a 6.123 inch connecting rod. CP Pistons are well-known for their robust construction, often utilizing advanced forging techniques to create pistons that can withstand the high pressures and temperatures found in performance applications. The material choice and forging process contribute to a strong, lightweight piston that reduces reciprocating mass, allowing your engine to rev more freely and reliably under demanding conditions. Because these are made to order, you can be confident they are built to the tightest tolerances for optimal performance and longevity.
This is a set of 8 pistons. Please note that these pistons are made to order and are non-cancelable once the order is placed. They are also not CARB approved and cannot be shipped to California. Always consult your engine builder or a professional mechanic to ensure these pistons are the correct choice for your specific engine build and application.
