CP Piston BRS Chevy LS7 4.155 Bore 4.125 Stroke 6.125 Rod 1.055 Set Of 8 (MTO Non-Cancel)

This is a set of eight CP Pistons BRS series pistons, specifically made for Chevy LS7 engines. You get pistons with a 4.155-inch bore, a 4.125-inch stroke, and a 6.125-inch connecting rod length, featuring a 1.055-inch pin diameter. These pistons are built for high-performance applications where strength and reliability are key. They are made to order, meaning they are manufactured specifically for your purchase, so please allow for production time and note that these orders cannot be canceled once placed.

CP Pistons is known for its well-built forged pistons, and this BRS series is no exception. Forged from high-strength aluminum alloys, these pistons are designed to withstand the extreme pressures and temperatures found in powerful V8 engines. The BRS series often incorporates advanced skirt coatings to reduce friction and wear, contributing to improved engine longevity and performance. The specific dimensions – 4.155" bore, 4.125" stroke, and 6.125" rod length – indicate these are intended for a stroker crankshaft setup, pushing the displacement beyond the stock LS7. The 1.055" pin diameter is a common size for robust racing applications.

When building or rebuilding a high-performance LS7 engine, choosing the right pistons is critical. These CP Pistons offer a solid foundation for significant power gains. Keep in mind that due to their specialized nature and made-to-order status, these pistons are not CARB approved and cannot be shipped to California. Ensure you have the correct supporting components, such as matching connecting rods and a crankshaft, to complete your engine build.
