R&D Yamaha SHO/FZR 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 stock 8.6-1 or 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.

R&D recommends upgrading to our High Performance Pistons and Rods in applications producing over 300 H.P. @ sustained RPM's 8,000+.
  • • Direct replacement piston kits for High H.P. applications
  • • High quality forged materials replace low performance cast
  • • Improved ring seal with Nascar Style ring sets
  • • Increased RPM’s and horsepower by reducing weight
  • • Works great with high boost compressor wheels and turbo kits
  • • Retains O.E.M. wrist pins
