CP Piston BRS All Chevy LS 4.070 Bore 4.000 Stroke 6.125 Rod Set Of 8 (MTO Non-Cancel)

Forged from 2618-T61 aluminum, these CP-Carrillo pistons are built for serious performance in Chevy LS engines. The 4.070-inch bore and 4.000-inch stroke combination is a popular choice for building larger displacement LS powerplants, often paired with a 6.125-inch connecting rod for optimal geometry and piston dwell. This set is designed for builders looking to push the limits of their LS engine, whether for track use, extreme street builds, or competition.

CP-Carrillo is known for its robust piston designs, and this set is no exception. The 2618-T61 aluminum alloy offers a strong yet lightweight foundation, capable of handling the high cylinder pressures and temperatures associated with boosted or high-compression naturally aspirated builds. The specific design of the BRS series pistons incorporates features aimed at improving ring seal and reducing friction, which translates to more efficient combustion and improved power output. These are made-to-order, meaning they are custom-built to your specifications, ensuring a precise fit and performance tailored to your engine's needs.

Because these pistons are made-to-order, they are non-cancelable and non-returnable once production begins. Please verify your engine specifications and desired configuration before ordering. This set is not CARB approved and cannot be shipped to California. Ensure you are aware of all local emissions regulations before purchasing.
