Thank you for viewing. Mini 4WD MRF Response Up Gear (G-22) This is a Response Up Gear (G22) made by MRF, a well-known custom shop in the Mini 4WD world. I planned to use it after purchase, but I stopped doing Mini 4WD and have been storing it. The following is an explanation of the gear ↓↓ This is a modified version of the G-22 spur gear for double-shaft motors, processed so that the shaft fits tightly without play when passed through the hexagonal hole. By applying this modification, there is almost no play between the shaft and the gear when using "hollow shafts, black reinforced shafts, normal shafts," etc. Because there is no play, the drive is transmitted directly, improving the response when accelerating after a section. * Some thicker shafts, such as titanium shafts, may require some pressing. Processed with a dedicated jig + high-pressure press machine Processing with even pressure, No selection is made during processing, All opened items are processed to be tight, so those who want to select should do so as needed. Although it is a new, unused product that has been processed, it is only processed in the same way for gears that are already out of alignment from the beginning, so please understand that this product depends on the original precision. This item is available for immediate purchase. Please feel free to contact me if you have any questions. #MS Flex #Spur Gear #Mini 4WD #Processing #Custom
