MRE offers a huge line of rotating assemblies to handle anything from your basic street cars, to all out race engines. Pricing will depend on the power level you are building for. Each assembly is balanced to within a 1/2 of a gram for real smooth operation at any rpm. We also custom design balanced rotating assemblies to fit any and all of your needs. Beware of some companies offering real low dollar rotating assemblies as most of them may contain no-name or blem parts, and are not balanced correctly. We have messed with many so-called "cheap" assemblies, and they cost more in the long run to get them usable.We match each rod and piston to the lightest one and balance each crank accordingly. Our assemblies are checked and double checked to make sure each part used will fit your horsepower needs with complete reliability.
