Mini 4WD Original Wheel Puller ver.2 + Reinforced Arm Specification If there is a 1mm clearance between the chassis and the tires, it works for 26mm to small diameter wheels. It can be removed with just a few squeezes. Pushing the orange button releases the stopper. Due to customer requests, the plate is made of 1mm stainless steel processed by laser to support reverse-mounted wheels. This ensures high precision and has minimal impact on the bumper shape. It also comes with a reinforcement plate for increased strength. The shaft does not rotate, making it less likely to slip, and it slips even less with hollow shafts. Even juniors can easily remove wheels, and users have given high ratings for its ease of use. Please note that there may be scratches from the manufacturing process, but this does not affect usability. This item is also being sold elsewhere, so it's first come, first served.
