This is the Dave's Motors 30mm Stuffer Stroker Crankshaft (+2mm from stock) for use in Zenoah and CY engines. This is perfect for use with the 30.5cc big bore kit (RCS-CC254) to increase performance in your HPI Baja 5B buggy, 5T, or 5SC truck.
Be sure to check your squish clearance after installing this crankshaft to prevent engine damage. You will likely need to use additional base gaskets 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).
