GP Piston Ring Set 4.040 Bore 1/16 1/16 3/16

The GP Piston Ring Set 4.040 Bore 1/16 1/16 3/16 from TOTAL SEAL is designed for serious engine builders and performance mechanics who are working on high-compression builds and significant displacement increases. This ring set is specifically engineered for 4.040-inch bore applications, making it ideal for a variety of performance engines.

Constructed with precision ring groove geometry, this set features a 1/16-inch top ring, a 1/16-inch second ring, and a 3/16-inch oil ring configuration. This combination is proven to provide optimal blow-by control and efficient oil return, ensuring durability and sealing integrity under high thermal stress and combustion pressures. The GP line utilizes proprietary ductile iron and advanced coating technology to minimize wear and maximize sealing efficiency.

Ideal for hot rod builders, drag racers, and street performance enthusiasts, this piston ring set is compatible with late-model Chevy, Ford, Mopar, and LS platforms. Its design ensures proper clearances and ring tension for modern overbored blocks, preventing excessive side clearance that can compromise compression and increase oil consumption.
