Hobbyists wanting better consistency from 1/12 and 1/10 pancars will find the Arrowmax AM-931011 Pancar Geardiff Hub Insert a useful tuning part. It helps the gears mesh cleaner so throttle and steering inputs feel more predictable on track.
This hub insert is crafted to fit typical gear diffs used in pancar builds and will improve internal gear engagement for many 1/12 and 1/10 models. Enhanced gear contact helps maintain traction during high speed sections and tighter corners.
Installation is straightforward and suited to home tuners, requiring no specialist workshop equipment. The insert is easy to swap in during a diff service, making it a handy mod for weekend racers and club drivers.
