Stuffer Crankshaft with +2mm Stroke

2mm stuffer stroker crank - increases the cc's of your motor. 30mm stroke - 2mm longer than stock 28mm stroke for most RC-style motors. Forged, heat treated, and ground. Journal diameter same as stock G230RC crank. Built in stuffer reduces crankcase volume, increasing primary compression. Be sure to check your squish clearance after installing this crankshaft to prevent engine damage. You will likely need to use additional base gaskets or an additional .040 copper gasket to allow for proper clearance. Fits Zenoah G23LH / G230RC / G260RC. Also fits Chung Yang / CY23RC / CY26RC / CY27RC / CY29RC / GP290 engines. Fits directly into the CY29RC engine with no modifications (the CY29RC uses a 30mm stroke crankshaft in stock form).
