CP Piston BRS Chevy LS 4.070 Bore 3.622 Stroke 6.125 Rods 1.305 Ch Set Of 8 (MTO Non-Cancel)

This set includes eight CP Pistons BRS series pistons, designed for Chevy LS engines. Each piston features a 4.070 inch bore, a 3.622 inch stroke, and is built to pair with 6.125 inch connecting rods. The compression height is 1.305 inches. These pistons are made from a strong aluminum alloy, chosen for its lightweight properties and ability to withstand high performance demands. The BRS series is known for its robust construction, suitable for builds where durability and consistent performance are key. Each set comes complete with the necessary wrist pins, locks, and rings, ensuring you have the essential components for installation. Remember, these pistons are made to order and cannot be canceled once the order is placed, so please confirm your specifications carefully before purchasing.

When building or rebuilding a high-performance LS engine, the pistons are a critical component. CP Pistons uses advanced forging techniques to create pistons that are both strong and lightweight, which helps reduce reciprocating mass and allows the engine to rev more freely. The specific design of the BRS series aims to provide improved combustion efficiency and durability under demanding conditions. The 4.070 inch bore size is common for many popular LS engine displacements, and the 3.622 inch stroke combined with the 6.125 inch rod length creates a specific rod-to-stroke ratio that influences engine characteristics. The 1.305 inch compression height is also a key measurement that determines the piston's position in the cylinder at Top Dead Center, affecting the final compression ratio when used with your chosen cylinder heads and crankshaft.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning. Given these are made-to-order, allow for production time before shipping.
