A spacer that offsets the rear sprocket 4mm outward. By offsetting the chain line 4mm outward, you can install an 8 inch 4.0J wheel on the stock swing arm. Can also be installed on standard width swingarms. Please remove the stud bolt from the genuine hub and replace it with the included stud bolt. Be sure to use it in conjunction with the 4mm offset sprocket on the front. This product is designed and manufactured based on the genuine Monkey/Cub 50cc engine. Please note that incorrect installation may cause damage. *For Monkey genuine drum hub only. (Cannot be used with non-genuine hubs such as disc hubs) *If you install a 120 size tire, the chain cover and tire will interfere, so please process by cutting the interference area. *Screw the stud bolt up to 16mm from the sprocket seat. *In the case of a normal swing arm, the welded part of the suspension receiving bolt may occasionally interfere with the lock nut. In this case, please process the welded part by cutting it. [Material] A6061 material [Surface treatment] Silver anodized finish
