R&D Ultra Forged Racing Piston Kits have been developed for the hard core race enthusiasts or precision engine builders who are looking to gain maximum horsepower and reliability from their racing engines. R&D offers high quality forged aluminum, heat treated, and CNC machined racing pistons in 9.5-1 compression ratios to replace O.E.M. cast aluminum pistons known to break, crack, or shatter in high performance, high heat conditions. High horsepower marine engines with high boost pressures are more prone to have detonation over conventional racing engines due to sustained loads. Forged pistons in marine applications are a must. What ever performance platform you are planning to build, trust the pros at R&D with all your compression ratio, boost, and engine management needs or questions.
