CP Piston BRS Chevy 403Ci Al LS Bore 4.010 Stroke 4.000 Rod 6.125 Set Of 8 (MTO Non-Cancel)

This is a set of CP Pistons BLS1148-010 forged pistons, specifically made for Chevy LS engines. These pistons are designed for a 4.010 inch bore, a 4.000 inch stroke, and use a 6.125 inch rod length, creating a 403 cubic inch displacement. CP Pistons are well-known in performance circles for their robust construction and attention to detail, making them a solid choice for engine builds where reliability and performance are key.

Forged pistons like these are built from a solid block of aluminum that's heated and hammered into shape, which makes them significantly stronger and more durable than cast pistons. This strength is crucial for engines that will see high cylinder pressures and temperatures, such as those found in performance street cars, race cars, or heavy-duty applications. The BLS1148-010 set is made to order, meaning they are manufactured specifically for your purchase, ensuring you receive a fresh, high-spec component. This process also means they are non-cancelable once ordered, so double-check your specifications before confirming your order.

This set includes eight pistons, enough for a standard V8 engine. Because these are a made-to-order item, please allow for additional production time. It's also important to note that these pistons are not CARB approved and cannot be shipped to California. For any engine build pushing the limits, investing in strong, well-made internal components like these CP Pistons is a critical step toward achieving your performance goals and ensuring long-term engine health.
